European Parliament tie-up complicates Cameron's reform push

"The risk is that it [Conservative MEPs aligning with right-wing parties in the European Parliament] is going to make it more difficult to get concessions out of the (European) Commission and the (European) Council in terms of Britain's reform agenda," said Stephen Tindale, an associate fellow at The Centre for European Reform think tank.

"His [Cameron's] MEPs (European lawmakers) are in alliance with some pretty unpleasant characters and that is going to make it more difficult to have a constructive conversation... Conservative MEPs are going to have to be taking a very hard line on issues like free movement".
