An ex assistant to Cameron was on 5Live yesterday.
When a PM goes anywhere (personal holiday or not) he/she will have a plethora of assistants etc with them. As well as armed minders and such like.
The PM was in communication with the US/FR presidents, Merkel and the Iraqi PM whilst over seas.
That is standard practice.
But hey, he didn’t respond to a pointless opposition leader at the click of their fingers......
