A very poor display by a professional.
Whether you like the PM or not is irrelevant BUT the PM represents the people of the UK and as such he should be treated with the respect the office deserves.
Whether he personally is deserving of that respect is something else BUT that office warrants respect which the VC winner has failed to do.
No doubt there will be some say he was appointed and not elected as he did not stand for election on that basis, it was clear however prior to last election that Blair would stand down.
However I would also refer people back to WW2 and note that Winston Churchill did not stand for election as a potential PM in the General Election pre WW2, nor indeed did John Major during the build up to Gulf War 1.
As a serving member of HM forces he doesn't get to decide who he likes in the leadership above him. His only input is at election time when he can vote for which ever candidate he wants or none at all.
The willingness to go to press sets a dangerous precedent as what happens when a serving soldier goes public and slates the Head of the Armed Forces because he is from RAF and doesn't understand the Army.
