PM admits he made mistake in choice of ambassador as he makes high-stakes statement to parliament over scandal

Keir Starmer has accused Olly Robbins of deliberately and repeatedly obstructing the truth about the Mandelson vetting scandal before a high-jeopardy appearance of the sacked top official before MPs on Tuesday.

Six days after the prime minister said he had learned that his pick for Washington ambassador had failed security vetting, Starmer admitted his decision to appoint him had been a fundamental mistake.
