Foreign Office officials said Rishi Sunak should attend D-day event, book reveals

Department twice provided written advice to No 10 before mistake that came to define Sunak's election campaign

Senior officials at the Foreign Office repeatedly warned No 10 that Rishi Sunak should not leave June's D-day commemoration in Normandy early, according to new revelations in a book about the Tories' 14 years in power.

The department passed on two messages to Downing Street in the weeks leading up to the event, which were then ignored in what has gone down as the worst election campaign blunder of the last 14 years.
