As some dude on the internet said,
On 4 January 1642 King Charles I entered the House of Commons to seize five 'disruptive' members, Lenthall behaved with great prudence and dignity. Having taken the speaker's chair and looked round in vain to discover the offending members, Charles turned to Lenthall standing below, and demanded of him whether any of those persons were in the House, whether he saw any of them and where they were. Lenthall fell on his knees and replied: "May it please your Majesty, I have neither eyes to see nor tongue to speak in this place but as the House is pleased to direct me, whose servant I am here".
Since that day every speaker has followed his example. Bercow has abused his position, he is a vainglorious little man with a monstrous ego and should be shamed out of office for claiming to speak for Parliament and the people when he clearly doesn't.
The position is diminished, literally and figuratively, while stumpy Bercow occupies it.
