Acting Labour leader Harriet Harman said David Cameron "should remember he is talking about people, not insects" following his "swarms" comment.
She told the BBC the Prime Minister appeared to want to whip people up against the migrants.
Ms Harman also dismissed calls for the British Army to be sent in to sort out the problem.

I really would encourage you to look at Britain in a new way...
