Liz Truss has pulled out of a planned event this afternoon, during which she was due to take questions from journalists.

Downing Street has not given any reason for the canning of the trip to an electronics manufacturer.

It comes after the prime minister said she is “completely committed” to the pensions triple lock at a make-or-break PMQs on Wednesday – the first since she rowed back on almost all of her tax cuts.

Ms Truss made the commitment in the Commons despite new chancellor Jeremy Hunt on Monday explicitly ruling out agreeing to any further pledges, including the triple lock, ahead of 31 October when he will announce a medium-term fiscal plan. A Downing Street spokesman repeated it on Tuesday.
