Home secretary sought to restrict minister’s access to papers as she calls for his sacking

Row between Shabana Mahmood and Mike Tapp broke out after he wrote unauthorised article about immigration

A rift between Keir Starmer and Shabana Mahmood has deepened after it emerged the home secretary wanted to deny the migration minister, Mike Tapp, access to sensitive documents without her approval as she called for him to be sacked.

Downing Street said Tapp – who has been a loyal supporter of Keir Starmer – remained a minister but that the prime minister was taking advice on whether he broke the ministerial code on collective responsibility.
