The vast majority at Calais are economic migrants, not refugees, young, fit men fleeing from conscription and who want to get here for benefits etc
Donations taken to there are being burnt on bonfires because they want mobile phones, iPads and money not clothing, toiletries etc.
A local organisation took four transit vans full of donations which were scornfully refused, so brought it all back again. It included tents, sleeping bags, blankets, toiletries etc. The accompanying people were shocked and disgusted as well as disappointed, the donations have now gone to homeless charity in nearby city.
