Top Whitehall official had to apologise over alleged bad behaviour by Raab

Exclusive: Source says MoJ permanent secretary made move to prevent incident from escalating into formal complaint

Dominic Raab behaved so badly in a meeting with the Home Office during his first stint as justice secretary that his department's top official had to personally apologise to counterparts afterwards, the Guardian has been told.

Whitehall sources said the deputy prime minister, who is facing two official complaints over alleged bullying, had acted so badly and inappropriately" at a high-level meeting earlier this year that the permanent secretary at the Ministry of Justice (MoJ) was forced to call senior officials of the then home secretary, Priti Patel, to express regret.
