Theresa May has told the BBC she will feel a “mixture of pride and disappointment” when she leaves Downing Street in 12 days’ time.
In her final TV interview with political editor Laura Kuenssberg, the PM spoke of “frustration” at not seeing Brexit through and underestimating how “entrenched” MPs had become.
She said she had achieved an “enormous amount” in three years in the job.
But she was sorry having to leave when “there was more that I wanted to do”.
Mrs May and her husband Philip will depart Downing Street on 24 July, succeeded as prime minister by either Boris Johnson or Jeremy Hunt.
She was forced to announce her exit in May, amid a revolt by Conservative MPs
