Many more people than the leading Tories already identified are being investigated by the gambling regulator in relation to bets on the date of the general election, Sky News understands.
And in a major new development, the watchdog has widened its inquiries to investigate whether people with inside knowledge may have asked a third party to place a bet for them.
Sky News also understands that investigators have written to leading bookmakers asking for details of bets of £20 or more on the election date within days of Rishi Sunak announcing it on May 22.
The body carrying out the investigation, the Gambling Commission, already takes a close interest in political betting and carries out extra checks on bets by people connected with politics, Sky News has been told.
The gambling industry also regards politicians and those who work closely with them as PEPs, politically exposed persons who are people “entrusted with a prominent public function”.
That’s because these people generally “present a higher risk for potential involvement in bribery and corruption by virtue of their position and influence”, according to the Law Society.
It emerged on Saturday evening Nick Mason, the Tory party’s chief data officer, was the fourth Conservative candidate or official being investigated. He has taken a leave of absence and denies any wrongdoing.
Mr Sunak’s parliamentary private secretary Craig Williams, the Tory candidate for Montgomeryshire and Glyndwr, admitted last week to placing a “flutter” on the date of the election.
Home Secretary James Cleverly told Sky News’ Sunday Morning with Trevor Phillips he had been told “very, very clearly” to not discuss the investigation.
He added: “I’m not in any way going to defend people who placed bets on that.”
Asked whether there was a wider betting circle, Mr Cleverly said: “That’s not my understanding. My understanding is it’s a small number of individuals.”
He also said he has “no reason to believe” any ministers are involved in betting on the timing of the election.
What is the law around gambling?
There are strict rules around gambling, with the latest laws updated in 2005.
Section 42 of the Gambling Act 2005 deals with cheating and says a person commits an offence if they cheat at gambling or do “anything for the purpose of enabling or assisting another person to cheat at gambling”.
It adds: “It is immaterial whether a person who cheats improves his changes of winning anything, or wins anything.”
Cheating is defined as an “actual or attempted deception or interference in connection with the process by which gambling is conducted, or a real or virtual game, race or other event or process to which gambling relates”.
Someone found guilty of cheating at gambling can be imprisoned for a maximum of two years and/or fined, or six months in prison for a lesser offence.
Betting with insider knowledge is also not allowed as an MP, with the MPs’ code of conduct prohibiting members from “causing significant damage to the reputation and integrity of the house”.
A Gambling Commission spokesman said: “The Gambling Commission regulates gambling in the interests of consumers and the wider public.
“Currently, the Commission is investigating the possibility of offences concerning the date of the election.
“This is an ongoing investigation, and the Commission cannot provide any further details at this time. We are not confirming or denying the identity of any individuals involved in this investigation.”
A Conservative spokesman told Sky News: “As instructed by the Gambling Commission, we are not permitted to discuss any matters related to any investigation with the subject or any other persons.”

The UK economy grew by 0.1% between July and September, according to the Office for National Statistics (ONS).
However, despite the small positive GDP growth recorded in the third quarter, the economy shrank by 0.1% in September, dragging down overall growth for the three month period.
The growth was also slower than what had been expected by experts and a drop from the 0.5% growth between April and June, the ONS said.
Economists polled by Reuters and the Bank of England had forecast an expansion of 0.2%, slowing from the rapid growth seen over the first half of 2024 when the economy was rebounding from last year’s shallow recession.
And the metric that Labour has said it is most focused on – the GDP per capita, or the economic output divided by the number of people in the country – also fell by 0.1%.
Reacting to the figures, Chancellor of the Exchequer Rachel Reeves said: “Am I satisfied with the numbers published today? Of course not. I want growth to be stronger, to come sooner, and also to be felt by families right across the country.”
“It’s why in my Mansion House speech last night, I announced some of the biggest reforms of our pension system in a generation to unlock long term patient capital, up to £80bn to help invest in small businesses and scale up businesses and in the infrastructure needs,” Ms Reeves later told Sky News in an interview.
“We’re four months into this government. There’s a lot more to do to turn around the growth performance of the last decade or so.”
The sluggish services sector – which makes up the bulk of the British economy – was a particular drag on growth over the past three months. It expanded by 0.1%, cancelling out the 0.8% growth in the construction sector.
The UK’s GDP for the most recent quarter is lower than the 0.7% growth in the US and 0.4% in the Eurozone.
The figures have pushed the UK towards the bottom of the G7 growth table for the third quarter of the year.
It was expected to meet the same 0.2% growth figures reported in Germany and Japan – but fell below that after a slow September.
The pound remained stable following the news, hovering around $1.267. The FTSE 100, meanwhile, opened the day down by 0.4%.
The Bank of England last week predicted that Ms Reeves’s first budget as chancellor will increase inflation by up to half a percentage point over the next two years, contributing to a slower decline in interest rates than previously thought.
Announcing a widely anticipated 0.25 percentage point cut in the base rate to 4.75%, the Bank’s Monetary Policy Committee (MPC) forecast that inflation will return “sustainably” to its target of 2% in the first half of 2027, a year later than at its last meeting.
The Bank’s quarterly report found Ms Reeves’s £70bn package of tax and borrowing measures will place upward pressure on prices, as well as delivering a three-quarter point increase to GDP next year.
