A Bradford charity has told ITV Calendar that it is considering withdrawing its work from the Calais camps, claiming that too many people are there for the wrong reasons.
The UK Government has so far preferred to focus its attention on the camps in the countries bordering Syria. But the Prime Minister said that people should not be discouraged from donating aid to Calais if they wished to do so.
"There are some important charities working in Calais to help people there and if people want to donate to that part of the refugee crisis then they should. I would encourage people to give to responsible charities that can account for what they do."
He nevertheless defended the Government's record of helping those caught up in the refugee crisis.
"The right way to help the refugee crisis is to donate money to the Syrian refugee organisations including the work that is being done in Turkey and Lebanon and Jordan. We don't want to encourage people to make what is a very dangerous journey to Europe."
The Prime Minister said the people living in the Calais Jungle should talk to French authorities and put in an asylum claim there. He pointed out that Britain is 'building very strong borders around the tunnel and the Calais port', in an attempt to 'make sure that people who come to Britain have a right to come to Britain.'
