Top civil servant regrets holiday while Afghanistan fell to Taliban

Sir Philip Barton refused to say precisely when Raab had been on holiday in August

The head of the diplomatic service has admitted failing to show leadership after he began a three-week holiday two days before the Foreign Office internally accepted Kabul was about to fall to the Taliban.

Sir Philip Barton stayed on holiday until 28 August and during bruising evidence to the foreign affairs select committee, he admitted this was a mistake.
