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.
Taiwanese lawmaker Ko Ju-Chun has called on the government to consider adding Bitcoin to its national reserves, suggesting it could serve as a hedge against global economic uncertainty.
Ko, a legislator at-large in Taiwan’s legislative body, the Legislative Yuan, took to X on Friday to report that he had advocated Bitcoin (BTC) investment by the Taiwanese government at the National Conference on May 9.
In his remarks, Ko cited Bitcoin’s potential to become a hedge amid global economic risks and urged Taiwan to recognize the cryptocurrency alongside gold and foreign exchange reserves to boost its financial resilience.
Ko highlighted that Taiwan is an export-driven economy that has experienced significant fluctuations in its national currency, the New Taiwan dollar, amid global inflation and intensifying geopolitical risks.
“We currently have a gold reserve of 423 metric tons, and our foreign exchange reserves amount to $577 billion, including investments in US Treasury bonds,” the lawmaker stated.
In a scenario of more intense currency volatility or potential regional conflicts, Taiwan may “very likely be unable to ensure the security and liquidity,” Ko continued, adding that Bitcoin could be a great addition to Taiwan’s reserves for several reasons.

“Bitcoin has been operating for over 15 years. It has a fixed total supply, is decentralized, and is resistant to censorship. Many countries are focusing on its hedging attributes. At the same time, in intense situations, it may not face the risk of embargo,” he said.
Instead, the legislator suggested adding a “small proportion of Bitcoin” into the diversified assets as tools for sovereign asset allocation and risk hedging, and backup capacity of Taiwan’s financial system.
“When exchange rate risk and regional uncertainty increase, it is time to introduce new tools to construct a more flexible financial strategy framework,” Ko said, adding:
“As former Dean Chen Chong said, Bitcoin is the gun of the digital era. It may also be the gold of the digital era, the silver of the digital era. Or it could be gunpowder. A wise nation will not let weapons be in others’ hands.”
German law enforcement seized 34 million euros ($38 million) in cryptocurrency from eXch, a cryptocurrency platform allegedly used to launder funds stolen after Bybit’s record-breaking $1.4 billion hack.
The seizure, announced on May 9 by Germany’s Federal Criminal Police Office (BKA) and Frankfurt’s main prosecutor’s office, involved multiple crypto assets, including Bitcoin (BTC), Ether (ETH), Litecoin (LTC) and Dash (DASH). The move marks the third-largest crypto confiscation in the BKA’s history.
The authorities also seized eXch’s German server infrastructure with over eight terabytes of data and shut down the platform, the announcement added.
eXch exchanged crypto without AML
In the statement, the BKA described eXch as a “swapping” service that allowed users to exchange various crypto assets without implementing Anti-Money Laundering (AML) measures.
The platform had operated since 2014 and reportedly facilitated about $1.9 billion in crypto transfers, some of which were believed to be of “criminal origin,” including assets laundered during the Bybit hack.

“Among other things, a portion of the $1.5 billion stolen from the Bybit crypto exchange, which was hacked on Feb. 21, 2025, is said to have been exchanged via eXch,” the authorities wrote.
Multisig, FixedFloat among laundering cases
According to a post by crypto sleuth ZachXBT, eXch was also involved in laundering millions of funds from other crypto thefts and exploits, including Multisig, FixedFloat and the $243 million Genesis creditor theft.
Those were in addition to “countless phishing drainer services over the past few years with refusal to block addresses and freeze orders,” ZachXBT said.

ZachXBT was among the first security analysts to report on eXch’s links to laundering $35 million of crypto assets stolen from Bybit soon after the hack was confirmed.
“Lazarus Group transferred 5K ETH from the Bybit Hack to a new address and began laundering funds via eXch (a centralized mixer) and bridging funds to Bitcoin via Chainflip,” ZachXBT wrote in a Telegram post on Feb. 22.
“Even though we have been able to operate despite some failed attempts to shut down our infrastructure […], we don’t see any point in operating in a hostile environment where we are the target of SIGINT [Signals Intelligence] simply because some people misinterpret our goals,” it wrote.
Addressing the seizure, senior public prosecutor Benjamin Krause stressed the importance of action against “quick and anonymous opportunities for money laundering for any amount.”
“Crypto swapping is an essential component of the underground economy, used to conceal incriminated funds from illegal activities such as hacking or trading in stolen payment card data, thus making them available to perpetrators,” he said.
With Ruth away, Beth and Harriet are joined by Salma Shah, a former Conservative special adviser from 2014-2018 and now a political commentator.
They unpack Donald Trump’s surprise UK trade deal announcement and what it means for Sir Keir Starmer, who’s also landed a deal with India and is gearing up for key EU negotiations.
But while the global optics look strong, the domestic mood is tense. Harriet has some advice for the Labour backbenchers who are unhappy over welfare cuts and the winter fuel allowance policy.
