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 after Rishi 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.
Earlier this week, Tony Lee, the party’s director of campaigns, and his wife Laura Saunders, the Tory candidate for Bristol North West, were placed under investigation.
Mr Sunak’s close protection officer has been arrested for allegedly betting on the timing of the election.
