Parliament “always has the opportunity” to re-examine the rules on betting for politicians, Rishi Sunak has said, following calls for a ban similar to that for footballers.
The prime minister said gambling on elections was “not something I would do” as he argued the immediate priority was to establish any wrongdoing.

It comes after Sky News revealed Mr Sunak’s most senior adviser in Downing Street, Liam Booth-Smith, has been interviewed as part of the regulator’s probe, although sources stressed he was spoken to as a witness and was not a suspect.

Mr Sunak said: “I think the Gambling Commission is the body that is rightly placed to investigate any wrongdoing, I’ve been crystal clear that they should do that and they should make sure that anyone who has broken any rules should face the full consequences of the law – I will ensure they’re kicked out of the Conservative Party.
