CRASS David Cameron came under fire yesterday for branding families fleeing Syria’s civil war a “bunch of migrants.”

The Prime Minister was accused of “dehumanising” people caught up in a humanitarian crisis in order to score political points.

Campaigners and MPs said the fact that the comments came on Holocaust Memorial Day made them even more inappropriate.

It was the second time the Tory leader’s rhetoric on refugees has attracted condemnation — he described them as a “swarm” at the height of the crisis last summer.

His latest outburst came as he struggled to answer questions from Labour leader Jeremy Corbyn about Google’s tax avoidance.

In a cynical deflection technique, the Prime Minister sneered that Mr Corbyn has “met a bunch of migrants in Calais” at the weekend and “said they could all come to Britain.”

A Labour source, who had accompanied Mr Corbyn on the visit to Calais, said the comments “demonstrate an attitude that is wholly unnacceptable towards a humanitarian crisis on our doorstep.”

Yvette Cooper, who heads Labour’s refugee taskforce, called a point of order following Prime Minister’s questions.

She said: “The house will have heard many tributes made to Holocaust Memorial Day today and the Holocaust Educational Trust campaign doesn’t stand by.

“In that light and in that spirit, don’t you think that it was inappropriate for the Prime Minister to use language referring to the refugee crisis in Europe and talk about ‘a bunch of migrants’?”

Attempting to explain Mr Cameron’s comments, a Downing Street spokesman said he had been “making a point about Labour’s immigration policy.”

The spokesman claimed: “Labour now have a policy which is to open the doors to people who have reached Calais, just to let them into Britain.

“The PM believes that would make matters much worse.”

But Refugee Council head of advocacy Dr Lisa Doyle said: “When we are facing the greatest refugee crisis of our time, it is disappointing the Prime Minister is using flippant remarks to score political points.

“The Prime Minister should be showing political leadership and work with other European countries to ensure that people can live in safety and dignity.”
