Sunak burst into laughter when asked to name the date by presenter Amy Oakden, and insisted he had “answered that question many times in the last few weeks” and was “unfortunately not” able to disclose the precise date to local radio.

An unimpressed Oakden asked Sunak: “Why is that funny? Sorry. Why are you laughing about that?”

Sunak said he’d been chuckling “because there’s a way that we’d announce general elections and it would be done in the formal and official way.”

Sunak — whose party is trailing in the polls after 14 years in office — has already ruled out a May election, but said only that his “working assumption” is that there’ll be a vote in the second half of 2024.

He told BBC Radio Newcastle Tuesday that there had been “no change” to this position. Under British rules, Sunak must call an election no later than January 28 next year, but the precise timing before then is in his gift.

Sunak is not the first prime minister to struggle with the scrutiny of local radio broadcasters, who often ask questions that stray from the usual Westminster talking points. Sunak’s predecessor Liz Truss famously came under fire in a bruising local media round during her own short-lived premiership.
