David Cameron is facing demands to stop "dragging his feet" and allow more refugees into Britain after shocking pictures of a drowned Syrian boy triggered a backlash across Europe.
The Prime Minister has insisted that taking in more people will not solve the crisis wracking the continent, and the focus should be on bringing "peace and stability" to the war-ravaged areas they are fleeing.
But Labour is urging him to convene the Government's Cobra emergency committee, gather EU leaders for a summit, and agree to a parliamentary debate on the issue.
A number of Conservatives have added their voices to those demanding a shift in policy, with Mr Cameron being warned that he faces a "test of humanity" and must honour the British tradition of offering sanctuary to those in need.
