It is worth recalling just how much good will there was towards John Bercow when he became Speaker of the House of Commons in June 2009. Traumatised MPs had just been through the expenses scandal and many of them were feeling very sorry for themselves indeed. The famous Daily Telegraph investigation – based on a leaked computer drive and the unvarnished truth – had revealed that many MPs were at it in terms that infuriated those who paid their wages, the voters.

The previous Speaker, a friend of the then Prime Minister Gordon Brown, had been overwhelmed by the crisis and in highly unusual scenes he was forced out.
