LONDON — Britain's ruling Conservative party has become embroiled in a scandal concerning allegations that senior officials used inside knowledge to win bets on the date of the general election. Nick Mason, chief data officer for the Conservative Party, is the latest Tory official to be probed by the Gambling Commission, according to a report in The Sunday Times. CNBC was unable to immediately confirm this and the Conservative Party has not yet responded to a request for comment. Conservative MP for Montgomeryshire Craig Williams, who is also a close aide to the prime minister, was the first to face questions regarding a bet on the election date. The Conservative Party's campaign director Tony Lee, and his wife, Laura Saunders — the party's candidate in Bristol North West — are also being looked into by the Gambling Commission.
