The Tories have been forced to insist that they won't stitch up a post-election deal with the DUP, Nigel Farage's Reform UK or even the SNP to cling onto power.
The Prime Minister's press secretary repeatedly refused to say whether the Tories would enter a coalition or sign a less formal confidence and supply agreement if they fail to win a majority.
It came moments after Mr Sunak goaded Keir Starmer at PMQs for being "busy plotting coalitions".
