Debate on the conclusions of the European Council meeting of 18 and 19 February 2016 © EU 2016 - European Parliament 

Leaders of the main political groups in Parliament welcomed a fair EU-UK deal as an offer to the British people to remain in the EU. But it's an "in or out" vote some said, not another phase in the negotiations. During the plenary debate on the outcome of the recent EU summit with European Council President Donald Tusk and Commission President Jean-Claude Juncker, many UK MEPs voiced arguments for and against EU membership.
