Bercow is a buffoon.
As has previously been said, the speaker's role is a politically neutral role and therefore he should have kept schtum. Given that he is a keyholder to Westminster Hall, he wields power over who can speak there anyway so there was no need for his posturing - but let's face it, Bercow always has liked to court publicity, and has always considered himself to be more important than that of the historic role of Speaker.
The thing that irritates me above all else though is the hypocrisy of Bercow. Talbot posted links to the fact that the Chinese President was welcomed (and we all know what a tolerant country that is), and the Emir of Kuwait was welcomed, a country that bans Israelis and treats its women as second class citizens. It was interesting that despite prompting Mikey was incredibly silent about Talbot's links.
