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 22 May.
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.”

An elderly British couple who were detained in a maximum security Taliban prison have arrived in the UK.
Barbie Reynolds, 76, and her husband Peter, 80, landed at Heathrow Airport on Saturday.
The couple were detained by the Taliban’s interior ministry on 1 February as they travelled to their home in Bamyan province, central Afghanistan.
They had been held without charge before being released from detention on Friday and flown to Qatar, where they were reunited with their daughter.

Freed couple reunites with daughter
Richard Lindsay, the UK’s special envoy to Afghanistan, previously told Sky News it was “unclear” on what grounds the couple had been detained.
The UK government advises British nationals not to travel to Afghanistan.
Abdul Qahar Balkhi, a spokesperson at the Talibangovernment’s foreign ministry, said in a statement posted on X that the couple “violated Afghan law” and were released from prison after a court hearing.
He did not say what law the couple were alleged to have broken.
Sky correspondent Cordelia Lynch was at Kabul Airport as the freed couple arrived and departed.

Sky’s Cordy Lynch speaks to released couple
Mr Reynolds told her: “We are just very thankful.”
His wife added: “We’ve been treated very well. We’re looking forward to seeing our children.
“We are looking forward to returning to Afghanistan if we can. We are Afghan citizens.”
The couple have lived in Afghanistan for 18 years and run an organisation called Rebuild, which provides education and training programmes.
They have been together since the 1960s and married in the Afghan capital in 1970.
More than 1,000 people crossed the Channel to the UK in small boats on Friday – the day after the first migrant was deported under the “one in, one out” deal.
The latest Home Office figures show 1,072 people made the journey in 13 boats – averaging more than 82 people per boat.
The number of people who have made the crossing so far in 2025 now stands at 32,103 – a record for this point in a year.
Ministers hope the deal will act as a deterrent, showing migrants they face being sent back to France.
But the scale of Friday’s crossings suggested the policy was so far having little effect on those prepared to make the risky crossing across the Channel.

France deportations will ‘take time’, Peter Kyle said on Friday
The deal with France means the UK can send migrants who enter the UK on small boats back to France.
For each one returned, the UK will allow an asylum seeker to enter through a safe and legal route – as long as they have not previously tried to enter illegally.
The first flights carrying asylum seekers from France to the UK under the reciprocal aspect of the deal are expected to take place next week.
Although they would not comment on numbers, a Home Office source told the PA news agency they were expected to be “at or close to parity”, given the “one in, one out” nature of the deal.
The agreement came into force on 5 August, having been signed by both countries and approved by the European Commission.
Former British athlete Lynsey Sharp has told Sky News she would have won a bronze medal at the Rio Olympics in 2016 had today’s gender testing rules been in place then.
Sharp came sixth in the women’s 800m final behind three now-barred athletes with differences in sexual development (DSD).
She told sports presenter Jacquie Beltrao the sport has changed considerably from when she was competing.
“Sometimes I look back and think I could have had an Olympicmedal, but I gave it my all that day and that was the rules at the time,” she said.
“Obviously, I wish I was competing nowadays, but that was my time in the sport and that’s how it was.”

The Rio women’s 800m final saw South Africa’s Caster Semenya take gold, with Burundi’s Francine Niyonsaba and Margaret Wambui winning silver and bronze respectively. All three would have been unable to compete today.
Semenya won a total of two Olympic gold medals before World Athletics introduced rules limiting her participation in the female class.

In a major policy overhaul introduced this year, World Athletics now requires athletes competing in the female category at the elite level of the sport to take a gene test.
The tests identify the SRY gene, which is on the Y chromosome and triggers the development of male characteristics.
The tests replace previous rules whereby athletes with DSD were able to compete as long as they artificially reduced their testosterone levels.

From March: Mandatory sex testing introduced for female athletes
Sharp says while she was competing, governing bodies “didn’t really deal with the issue head on”, and she was often portrayed as a “sore loser” over the issue.
Despite running a Scottish record in that race, her personal best, she described the experience as a “really difficult time”.
“Sadly, it did kind of taint my experience in the sport and at the Olympics in Rio,” she said.
Sharp added that despite the changes, it remains a “very contentious topic, not just in sport, but in society”.
Boxing has now also adopted a compulsory sex test to establish the presence of a Y chromosome at this month’s world championships.
The controversial Olympic champion Imane Khelif, who won Olympic welterweight gold in Paris 2024 in the female category, did not take it and couldn’t compete.
She has appealed to the Court of Arbitration for Sport against having to take the test.

Sharp’s comments come as British athletics star and Olympic champion Keely Hodgkinson is tipped to win her first world title in Sunday’s women’s 800m final at the World Athletics Championships in Tokyo.
She is returning from a year out after suffering two torn hamstrings.
