AFP, London :Tens of thousands of people marched through London in protest against Britain’s refugee policy on Saturday, with new Labour Party leader Jeremy Corbyn attending in his first political engagement only hours after being elected.The march to Parliament Square, which went past Prime Minister David Cameron’s Downing Street office, urged solidarity with the huge numbers entering continental Europe.Marchers on the peaceful rally danced to music, blew whistles and waved placards reading: “Refugees welcome here”, while others read: “No human being is illegal”, “Open the borders”, and “Refugee lives matter”.Demonstrators hold placards as they pass the Houses of Parliament during a pro-refugee rally in central London on September 12, 2015.

You deserve a safe and happy life. We welcome you here with open arms”.Another marcher, Dusan Petkovic, told AFP: “This rally is making clear that the government is wrong in their stance towards refugees.”Britain is not participating in a European Union quota system to share out refugees who have already reached Europe.Petkovic dismissed the 20,000 figure as “pathetic” with more than four million Syrians fleeing the four-year civil war.Another demonstrator, Marc Faux, said Britain’s response, over the next five years, was “ignoring the problem we have right now”.’I’ll be your friend’At the rally, a boy dressed as Paddington Bear had a sign saying: “Paddington Bear Was A Refugee”.A little girl held up her drawing of two hands clasped together with the words: “Help Syria” and “I’ll be your friend”.One man chalked “No more deaths in the sea” on the ground.
