Anthony Lee, a former director of campaigning for the Conservative Party, has pleaded guilty to two counts of cheating at gambling using inside information.
The charges relate to bets placed on the date of the 2024 UK General Election, in breach of the Gambling Act 2005.
Lee admitted two offences under section 42(1)(a) and section 42(1)(b) of the Gambling Act 2005 at Southwark Crown Court on 10 September.
His wife, Laura Lee, also appeared in court on the same day and pleaded guilty to one offence under section 42(1)(a) of the same legislation.
Anthony Lee had leaked confidential information to his wife regarding when then Prime Minister Rishi Sunak planned to call the general election.
Laura Lee, who was serving as a parliamentary candidate at the time, used that information to place bets on the election date.
Both Anthony Lee and Laura Lee are due to be sentenced in October, following their guilty pleas entered at Southwark Crown Court.
Amy Hind, wife of Conservative deputy digital director Anthony Hind, also pleaded guilty to cheating on the date of the election after receiving confidential information it would be called.
Hind had been working as a business support manager for the NHS at the time of the offence, though she previously held several roles within the Conservative Party, and is due to be sentenced on 23 October.
Former MP Craig Williams, who served as Sunak’s closest parliamentary aide, had already pleaded guilty in June and is awaiting sentencing at a later date.
Prosecutors revealed that Williams bet £250, £100, and £22.50 on the date of the 2024 election, telling the court he “used highly sensitive and confidential information.”
When details of the scandal first emerged in June 2024, Williams admitted making a “huge error of judgment” in placing those wagers.
Sunak’s decision to call the general election came as a surprise to many, including a significant number of Conservative MPs who had expected an autumn date to be chosen.
Questions still remain over approximately 10 other individuals accused of cheating in connection with election betting, widening the scope of the scandal considerably.
Those accused include former Conservative Party chief marketing officer Simon Chatfield, ex-chief data officer Nick Mason, and MP candidate Laura Saunders.
Tory Welsh Parliament member Russell George, former special advisor Jacob Willmer, and former police officer Jeremy Hunt have also been indicted in connection with the case.
The trials of the remaining 10 defendants are scheduled to take place across two separate proceedings in September 2027 and January 2028.
