Huw Merriman has been grilling the PM on the Liaison Committee
We've seen a lot of Conservative MPs share their letters of no confidence in the prime minister on Twitter - but the timing of Huw Merriman's stands out.
Merriman's letter was posted on Twitter while he was grilling Boris Johnson at the Liaison Committee.
It is not clear if Merriman sent the tweet or if someone else sent it on his behalf.
