Corbyn did, at times, vote against the party whip , this is not being disloyal to his party or party leader , neither was his campaign against the Iraq war disloyal to his party, as a pacifist how could he vote for bombing hell out of a country?
He did not whisper into the ear of political commentators , he attended party conferences, I attended a few fringe meetings he spoke in over the years , he did not make a point of leaving the conference before the leader made his speech
There is a difference between openly disagreeing with the leader to munching on sour grapes and plotting to knife the leader in the back, they should cross the floor or respect the fact they are voted in as MP's by grass root members as Corbyn was voted in as party leader by grass root members
