A fifth of Conservative MPs will vote for Britain to leave the European Union regardless of the outcome of David Cameron's negotiations with Brussels, polling has found.

Some 11% of Tories intend to vote to stay in whatever settlement the Prime Minister secures while 61% of the party's MPs plan to decide after an agreement has been reached, the research by Ipsos Mori found.

Across the Commons, half of MPs will vote to remain in the EU and 11% to quit, the study for the UK in a Changing Europe research organisation found.

Just 16% of Tories believe Mr Cameron will achieve "a great deal" in the talks to secure reforms to Britain's relationship with Brussels with nearly four in ten (38%) of his party expecting "not very much".

But 64% of Conservatives believe voters will opt to stay in the EU, rising to 70% across the parties.

The EU means bureaucracy for 77% of Tory MPs and not enough control at external borders for 64%. For 82% of Labour MPs it means freedom to travel, study and work anywhere in Europe and economic prosperity for 74%.

Some 69% of Conservative MPs feel uneasy about the EU while a quarter feel angry and 16% disgust. The union sparks feelings of hope for 64% of Labour MPs, pride in 42% and happiness for 37%.

Nearly half of voters feel uneasy about the EU but the next strongest emotion was hope (26%) while a quarter were indifferent.

Professor Anand Menon, UK in a Changing Europe director, said: "This survey shows, on balance, MPs views are out of sync with the general public's views on the EU.

"For most people the EU stirs little to no emotion and it isn't an issue they are generally concerned about. Politicians clearly have a lot of work to do to convince people of the importance of getting engaged with the upcoming referendum and convincing them to come out to vote."

Just eight MPs knew that Luxembourg held the presidency of the Council of the European Union at the time they were asked.

Professor Menon said: "Our elected representatives displayed a surprising degree of ignorance coupled with, paradoxically, remarkably strong opinions about the EU. This highlights the importance of our initiative which exists to provide people with impartial information ahead of the UK's EU referendum."

:: A sample of 98 MPs, 49 Conservatives, 40 Labour, 8 SNP and 1 from other parties, were interviewed between 6 November and 18 December 2015. Interviews were conducted face-to-face and the data was weighted where necessary to reflect party balance and ministerial status.
