John Bercow was possibly the best Speaker that there's ever been in the House of Commons.
He was determined to ensure that the Government ALONE must NEVER be allowed to run the country, as that's the job of Parliament AS A WHOLE. Otherwise the system would break down and there would be no point in having Opposition MPs (and dissident MPs from the so-called 'governing' party) sitting in the house at all.
He quite rightly stuck to the over-riding principles of the way that Parliament must be run and, like all good leaders, he quite rightly didn't give a damn about whom he upset along the way. Good for him!
He doesn't just deserve a knighthood. He deserves sainthood!
