There, a delegation called on the prime minister for the immediate withdrawal of British troops from Afghanistan. "(They handed over) a letter from military families calling on the prime minister to bring the troops home to avoid any other families suffering tragedies in the way they have," organiser Kate Hudson said. BBC correspondent Ben Ando, in Trafalgar Square, estimated about 1,000 people had been at the protest and said organisers would be "disappointed" at the turnout. But Chris Nineham, of the coalition, said: "We have had a good turnout. "Once again it is an expression of the overwhelming opinion in this country which is against the war." Speakers addressing the crowds in Trafalgar Square included Stop The War Coalition president Tony Benn, Wikileaks founder Julian Assange, activist Jemima Khan, journalist John Pilger, musician Brian Eno, comedian Mark Steel, a number of Labour MPs, and 106-year-old anti-war campaigner Hetty Bower.
