DOES Boris know his imperial measurements from his metric ones? Flummoxed PM goes red as he is quizzed by MPs during grilling.
MP for Montgomeryshire Craig Williams said he is resigning as parliamentary private secretary to the Chancellor of the Exchequer.
In a letter posted to Twitter, he said: 'After the recent vote of confidence, I had given my support to you, with one last benefit of the doubt. I believed it was right that we draw a line under previous events and focus on rebuilding trust with the public and focusing on delivering good policies.
'It has now become apparent over recent days, that this is becoming impossible.
'It is therefore with deep regret that I resign from your Government.'
