THE European Parliament could torpedo David Cameron’s plans to cut benefits for migrant workers, its president Martin Schulz said yesterday.

Tory PM Mr Cameron met German MEP Mr Schulz in Brussels in a bid to win support for his EU membership renegotiation proposals ahead of the make-or-break summit with member states’ leaders on Thursday.

Downing Street has claimed that any deal struck would constitute a “legally binding document under international law.” Mr Cameron is poised to call an emergency cabinet and name the date for the referendum on Friday if he secures a deal.

But parts of that deal, including restrictions on benefits, would still need to be passed by the European Parliament if Britain votes to remain in the EU.

Speaking after his meeting with Mr Cameron, Mr Schulz insisted that he could not guarantee that the so-called “emergency break” on in-work benefits for EU workers would be supported by a majority of MEPs. The veteran German social democrat said he would do his “utmost to find a fair deal.” But he added: “To be quite clear — no government can go to a parliament and say: ‘This is our proposal. Can you give a guarantee about the result?’ This is, in democracy, not possible.

“Therefore my answer is that the European Parliament will do the utmost to support compromise and a fair deal, but I can’t pre-empt the result.”

MEPs from the Green group are expected to reject the proposals, as is the Nordic Green Left, which drew comparisons with “Greece’s legitimate requests” for an economic  settlement.
