David Cameron will be given an ultimatum by Brussels that the country must join a controversial quota scheme to take new arrivals from Greece or Italy or face being stopped from using EU deportation rules to its advantage.

Eurosceptics last night accused the EU of ‘mafia-style blackmail’ to force the UK to submit to their refugee relocation plan.

The move will throw the Prime Minister’s renegotiation of Britain’s EU membership into turmoil ahead of the referendum.

Under the EU’s Dublin Regulation the UK is allowed to return migrants to their point of entry in the continent.

More than 12,000 people have been removed from Britain to other EU countries under these rules since 2003 – a figure the Home Office has boasted is ‘many more than we have received in return’.

However, Brussels officials plan to link the deportation scheme to its unpopular refugee quotas.
That would force those wanting to use the Dublin rules to sign up to the relocation scheme as well. So far Britain has been able to refuse to take part in the quota system because of its opt-out on asylum issues.
