He was sentenced to 10 weeks behind bars after he pleaded guilty to the assault by beating of 45-year-old Paul Fellows in Frodsham, Cheshire, in the early hours of 26 October.
He announced his resignation as MP for Runcorn and Helsby in a social media post on Monday, describing the assault as a “deeply regrettable incident” for which he had “rightly been punished”.
“I am sincerely sorry to Paul Fellows, my family, colleagues and constituents,” he added.
A by-election will now be triggered in Runcorn and Helsby, where constituents will vote to elect a new MP.

By-election a ‘big test’ for PM
It will be the first by-election since Sir Keir Starmer became prime minister, in what Sky News’ political correspondent Liz Bates said would be a “big test” in a seat where Reform UK came second last year.
“Losing it would be an unmitigated disaster given the 14,000 majority achieved last time round,” said Bates.
Amesbury came first in Runcorn and Helsby with 22,358 votes at the 2024 general election – equating to 52.9% of the electorate.
Reform UK came in second with 7,662 votes (18.1%) and the Tories in third with 6,756 votes (16%).
Reform has yet to announce a candidate, but Karen Shore, the deputy leader of Cheshire West and Chester Council, will run for Labour.
The Conservatives have opted for Sean Houlston, a membership services manager for the National Federation of Builders.

When will the by-election be?
Under parliamentary procedure, an MP cannot simply resign but must be disqualified from holding their seat.
To do this, they must apply for a role in the paid office of the Crown, meaning they automatically lose their seat because working for the Crown is not seen as impartial.
Titles include the crown steward and bailiff of the Chiltern Hundreds and the Crown Steward and Bailiff of the Manor of Northstead.
Rachel Reeves has now appointed Amesbury to be steward and bailiff of the Three Hundreds of Chiltern, meaning the parliamentary seat is officially vacant.
Once he does, the chief whip will put forward a motion to Lindsay Hoyle, the Commons speaker, to officially begin the process of disqualifying the MP – known as “moving the writ”.
The Speaker then puts the motion to MPs for a vote. If they agree, the writ passes through the Commons and ends up with the returning officer in the local constituency who oversees the by-election.
The writ is typically issued within three months of the MP resigning from their seat and in doing so, the date of the by-election is fixed.
It could potentially coincide with the local elections in May.
Tory leader Kemi Badenoch has dismayed green Conservatives by declaring the UK’s target to reach net zero by 2050 “impossible”.
In a speech on Tuesday, the Conservative Party leader is expected to tell what she says is the “unvarnished truth” that the net zero goal cannot be achieved without “a serious drop in our living standards or by bankrupting us”.
Ms Badenoch will say she is not making a “moral judgement” on net zero or debating whether climate change exists.
But, as she begins to renew party policy, she will say that current climate policies are “largely failing” to improve nature and “driving up the cost of energy”.
Net zero means cutting emissions of greenhouse gases, which cause climate change, to virtually zero, and absorbing the rest elsewhere.
Scientists say the world must reach that point by 2050 to avoid even worse flooding, wildfires, and other damage – but that action is lagging behind.
The UK has already cut its greenhouse gas emissions in half.
The next half is expected to be more challenging as it requires changes to people’s heating, cars and diet – things that often need upfront costs, but could save people money in the long run with the right government support, advisers have said.
Ms Badenoch’s plans take the Conservative Party to its most sceptical position on net zero yet – a target set in law by Tory Prime Minister Theresa May in 2019.

Kemi Badenoch heckled by climate protesters on Monday
Ms Badenoch’s “policy renewal” she is outlining on Tuesday will see shadow cabinet members set core priority questions as a move towards formulating new policy for the party.
Sam Hall, of the Conservative Environment Network of 50 MPs, said it was “a mistake” for Ms Badenoch to have “jumped the gun on her own policy review and decided net zero isn’t possible by 2050”.
He said the Tory leader was right to question Labour’s climate plans, but that the target is driven “not by optimism but by scientific reality; without it climate change impacts and costs will continue to worsen”.
Abandoning the science would risk losing voter’s support, he added.
This may be an inflection point for goodwill towards climate action in Tory Party
The UK public has long been supportive of government climate action – that’s true across voters of different parties too.
Labour capitalised on this in last year’s general election and swooped to victory with a green mandate.
Rishi Sunak’s attempts to roll back some climate policies flopped, and polling by More In Common found Labour’s arguments that clean power and climate action are the best way to tackle the cost of living cut through with people. For now, at least.
The tide of climate scepticism has been rising since Sunak’s days, with Reform UK questioning climate science altogether and Kemi Badenoch now calling the 2050 target “impossible” – though she did stress she doesn’t want to dismantle it and that she does believe in climate change. And she’s not wrong that it is going to be hard.
Given the strong public support for climate action, it’s not surprising Sunak’s attempt to politicise the issue didn’t work out for him.
But now others following in his footsteps have been emboldened by US President Donald Trump. Their attacks are gathering speed – and they might start to take root.
This may be an inflection point for goodwill towards climate action in the Conservative Party – which has a long legacy of supporting it – and more broadly in the UK.
Labour cannot take public support for its net zero plans for granted at a time when political consensus on it is fracturing.
And given the next stage of the country’s climate action is about to get more disruptive for people, it is just when it needs this public support more than ever.
Four in five Conservative voters in last year’s general election and two thirds of Reform voters thought it was important that the government cared about tackling climate change, according to polling by More in Common.
Shaun Spiers, executive director of thinktank Green Alliance, called it “disappointing” to see Ms Badenoch “turn her back on cleaner, cheaper, homegrown energy”.
“It is even more disappointing to see the leader of the opposition take cues from climate deniers across the pond,” he added, in a veiled swipe at President Trump.
“Net zero is not ‘nice-to-have’, it’s an achievable, evidence-based target designed to protect the UK from the worst impacts of climate change.”
But it also warned as Labour took office last summer that, at that time, just one third of the cuts to greenhouse gases needed to reach an interim 2030 target were covered by a “credible plan”.
Asset manager Hashdex has amended its S-1 regulatory filing for its cryptocurrency index exchange-traded fund (ETF) to include seven altcoins in addition to Bitcoin (BTC) and Ether (ETH), according to a March 14 filing.
The revision proposes adding seven specific altcoins to the index ETF — Solana (SOL), XRP (XRP), Cardano (ADA), Chainlink (LINK), Avalanche (AVAX), Litecoin (LTC), and Uniswap (UNI). As of March 17, the Hashdex Nasdaq Crypto Index US ETF holds only Bitcoin and Ether.
Previous versions of Hashdex’s S-1 suggested the possibility of adding other cryptocurrencies in the future but didn’t specify which ones.
According to the filing, the proposed altcoins additions “are decentralized peer-to-peer computer systems that rely on public key cryptography for security, and their values are primarily influenced by market supply and demand.”
The revised filing signals how ETF issuers are accelerating planned crypto product rollouts now that US President Donald Trump has instructed federal regulators to take a more lenient stance on digital asset regulation.
As part of the transition, the ETF plans to switch its reference index from the Nasdaq Crypto US Index — which only tracks BTC and ETH — to the more comprehensive Nasdaq Crypto Index, the filing said.
The asset manager did not specify when it plans to make the change. The US Securities and Exchange Commission (SEC) must sign off on the proposed changes before they can take effect.

In December, the SEC gave the green light to both Hashdex and Franklin Templeton’s respective Bitcoin and Ether index ETFs.
Both ETFs were listed in February, initially drawing relatively modest inflows, data shows. They are the first US ETFs aiming to offer investors a one-stop-shop diversified crypto index.
Asset manager Grayscale has also applied to convert its Grayscale Digital Large Cap Fund to an ETF. Created in 2018, the fund holds a crypto index portfolio comprising BTC, ETH, SOL and XRP, among others.
Industry analysts say crypto index ETFs are the next big focus for issuers after ETFs holding BTC and ETH listed in January and July, respectively.
“The next logical step is index ETFs because indices are efficient for investors — just like how people buy the S&P 500 in an ETF. This will be the same in crypto,” Katalin Tischhauser, head of investment research at crypto bank Sygnum, told Cointelegraph in August.
The filings, submitted by Cboe and other exchanges, addressed proposed rule changes concerning staking, options, in-kind redemptions and new types of altcoin funds.
The newly reintroduced Boosting Innovation, Technology, and Competitiveness through Optimized Investment Nationwide (BITCOIN) Act of 2025 by Senator Cynthia Lummis would allow the United States to potentially hold over 1 million Bitcoin (BTC) in its crypto reserves.
The bill directs the government to buy 200,000 BTC annually over five years, to be paid for with existing funds within the Federal Reserve and the Treasury Department.
If signed into law, the act would allow the US to hold more than 1 million BTC as long as the assets are acquired through lawful means other than direct purchases, including criminal or civil forfeitures, gifts, or transfers from federal agencies.
Democratic lawmaker urges Treasury to cease Trump’s Bitcoin reserve plans
US Representative Gerald Connolly, a Democrat from Michigan, called on the Treasury to cease its efforts to create a crypto reserve in the United States. The lawmaker said there were conflicts of interest with US President Donald Trump and argued that the reserve would not benefit Americans.
Connolly criticized the reserve in a letter addressed to Treasury Secretary Scott Bessent, arguing that there’s no “discernible benefit” to Americans and that the move would instead make Trump and his donors richer.
Argentine lawyer requests Interpol red notice for LIBRA creator: Report
Argentine lawyer Gregorio Dalbon is seeking an Interpol Red Notice for Hayden Davis, the co-creator of the LIBRA token, which caused a political scandal in Argentina.
Dalbon submitted a request, seeking the Red Notice, to prosecutor Eduardo Taiano and judge María Servini, who are investigating the involvement of President Javier Milei in the memecoin project.
In a filing, the lawyer said there’s a procedural risk if Davis remains free. The lawyer argued that Davis could have access to funds that might allow him to go into hiding or flee to the US.
America must back pro-stablecoin laws, reject CBDCs — US Rep. Emmer
In a House Financial Services Committee hearing, US Representative Tom Emmer said that central bank digital currencies (CBDCs) threaten American values. The lawmaker called on Congress to pass his CBDC Anti-Surveillance State Act to block future administrations from launching a CBDC without congressional approval.
Emmer said at the hearing that CBDC technology is “inherently un-American,” adding that allowing unelected bureaucrats to issue a CBDC could “upend the American way of life.”
Texas lawmaker seeks to cap state’s proposed BTC purchases at $250 million
Ron Reynolds, a Democratic state representative in Texas, has proposed a cap for the state’s investment in Bitcoin or other cryptocurrencies.
The lawmaker proposed in a bill that the state’s comptroller should not be allowed to invest more than $250 million in crypto. The bill also directs Texas municipalities or counties to not invest more than $10 million in crypto.
The proposed bill follows the Texas Senate’s approval of legislation establishing a strategic Bitcoin reserve in the state.
