The Jewish head of a centre-right think tank and a councillor in Westminster has defected from the Conservatives to Reform UK and will become their chief advisor on global affairs.

Dr Alan Mendoza, executive director of the Henry Jackson Society, now joins Councillor Laila Cunningham – tipped by some to be the party’s next candidate for mayor of London – as its second councillor in the central London borough.

“Britain today is in abject crisis”, Mendoza said, adding: “At home and abroad, our leaders seem determined to chart a course of national and international decline. But the British people deserve better than this.

"And, in Reform UK, we finally have a party who will put our interests first, and ensure that our tomorrow is better than our today.”
