This from Anne mcelvoy and Sam Coates is the best curtain-raiser on today in the Commons…

But stay for Sam’s exchange with the PM alongside Friday’s Paris summit:

“Prime Minister, why do you always end up sounding like the passenger in this government rather than the driver? Are you really expecting us to believe that a senior civil servant off his own back, without any sort of direction about the importance of Peter Mandelson being ambassador, unilaterally overruled security vetting to approve a political appointment and then made clear it was political?”

Sam had earlier in the exchange asked the Prime Minister if he was considering his position.
