The EU's reply to Cameron refusing to pay that £1.7 billion bill....
But Mr Barroso, who steps down as Commission president next month, said the bill should not "have come as a surprise". He said the UK's contribution had fallen in 2008 under the same mechanism.
"Of course I understand the concerns it has raised in London, but any person that wants to look at them with objectivity and honesty to the rules that were approved by the member states has to accept that sometimes these decisions happen," he told reporters in Brussels.
Pushed as to what would happen if the UK did not pay, he said: "I cannot speculate on non-payment.
"We cannot have a negotiation about the GDP of different countries... this should be left to independent statistics authorities."
He added that Eurostat, the EU statistics authority, which had come up with the calculation, was itself an independent body.
Im sorry remainers but voting to stay in bed with this lot, you may as well sell your soul to the devil himself.
