Perhaps Ken Livingstone’s comparison of Tiananmen Square with Trafalgar Square was a little bit ill advised. However hios point remains completely valid. Both T-Squares are comparable:
a) They are squares
b) They have a tradition of not always peaceful protest
Do you need any more? Frankly getting upset at ANYTHING Ken says is a hiding to nothing. He is a politician and he likes to be high profile. The rest just comes with the territory.
