David Cameron should apologise to the Greek people for saying he would close the borders to Greeks

Why is David Cameron being so disrespectful to the Greeks.Of course no other country wants immigrents but they dont go loud mouthing it to the Media and newspapers The Greeks have spent millions of pounds in the U.K and they have billions in their banks .The ordinary Greeks did not ask to be in the situationthey are today.If he wants to prove he is some kind of god or big man then he can give  the so called' ElginMarbles' that were stolen from Greece back.In that way the Greeks can be happy again
