Britain is "fulfilling its moral obligation" in relation to the victims of the crisis in Syria, David Cameron has said.
Labour has moved to force a vote on the acceptance of refugees into the UK, after an appeal by the UNHCR - the United Nations refugee agency - for Western countries to resettle 30,000 people.
Mr Cameron is under pressure to change his stance and accept more refugees.
Speaking to the BBC from the World Economic Forum in the Swiss resort of Davos, London Mayor Boris Johnson said Britain must "share the burden" with other countries.
