Amber Rudd has accused Boris Johnson of being a “backseat driver” over EU negotiations after his essay on Brexit re-opened Cabinet rifts.

The Home Secretary said that she did not want Mr Johnson “managing the Brexit process” and criticised his decision to go ahead with the article the day after the latest terrorist attack.

Ms Rudd also refused to deny that she has ambitions of succeeding Theresa May as prime minister, saying only that she has not “got time” to think about it.
