Such attacks have spiked since Hamas’ Oct. 7 massacre in Israel and its taking of more than 200 hostages.

But Duncan, who stepped down as an MP in 2019, claimed Tom Tugendhat, the U.K.’s security minister, disagrees with criticism of Israel’s settlement building — and urged his ouster. “How can you have a security minister in the British government, who does not believe in international law, when all this is going on? I think he should be sacked,” Duncan told LBC.

Tugendhat has been contacted by POLITICO for comment. His portfolio as security minister does not cover foreign policy, and he has not publicly spoken out against the U.K. government’s current policy on Israel, which is to condemn illegal settlement building.

Duncan also turned his fire on several other prominent Conservative figures in the CFI grouping, urging the House of Lords to remove two Tory peers — Stuart Polak and Eric Pickles — for “exercising the interests of another country, not that of the parliament in which [they] sit.”

The ex-minister meanwhile launched a broadside against Suella Braverman, a former Cabinet minister and standard-bearer of the Conservative right, for making a visit to Israel this week in a personal capacity.

He accused Braverman, who has spoken up in defense of Israel during her trip and urged the U.K. and U.S. to stop  “backsliding” in their support for the country, of supporting “the bombing and the annihilation of people in Gaza.”

In an interview with the BBC Thursday, Braverman branded suggestions Israel could be in breach of international law through its conduct in Gaza “absurd” and said it was “going above and beyond the necessary requirements to ensure that civilian casualties are limited, to ensure that aid is received onto the Gaza Strip and distributed.”
