Ooi, what is the procedure for dealing with an ambassador who's been "sidelined" ?. I presume it's recall and wait for another suitable post elsewhere? Some sort of advisory position for junior dips ?
He's not just an ambassador, he's the senior ambassador. HMA to the US is the most prestigious post in the FCO.
Which is why this whole issue is so worrying. HMG threw their top man under the bus - it'll be interesting to see if he's given anything in the Honours and Awards as means of thanks, as most HMA end up with a knighthood.
