Sir Keir Starmer is just about the most unpopular Prime Minister in history, when it comes to the Toby Jug-buying public.

He and 21 former occupants of No 10 have been immortalised by Staffordshire potters and the caricature mugs have been stocked on the shelves of the Houses of Parliament gift shop.

But latest figures show the Labour leader languishing third bottom in the sales league table – ahead of only Stanley Baldwin and Bonar Law, who were Tory PMs way back in the 1920s and 30s.

Each style of the £35 handcrafted 4.3-inch tall ceramic jugs made in Stoke-on-Trent have a limited edition of just 1,500.

Those of former Labour PMs Tony Blair, Jim Callaghan and Ramsay MacDonald have sold out, as have former Tory leaders David Cameron, Winston Churchill, Margaret Thatcher and Alec Douglas-Home – and even short-lived Liz Truss.

The shop’s current top five bestsellers are Boris Johnson, Harold Wilson, Theresa May, Clement Attlee and the “grey man of politics” John Major.
