Jacob Rees-Mogg has been elected as leader of an influential Eurosceptic group of Tory MPs and vowed to hold the Government to account over Brexit.

Eurosceptics said that Mr Rees-Mogg, who is stood unopposed to become head the European Research Group, is the ideal candidate for the role because he is a "true believer" in Brexit and the benefits it can bring for Britain.

It comes amid concerns that the group, which has more than 60 Eurosceptic Tory MPs, has recently been too weak and failed to do enough to challenge the Government.

Mr Rees-Mogg said: “I am delighted to have been elected in succession to Suella Fernandes and Steve Baker who were both superb Chairmen. In this role I am keen to help the Government implement the principles laid down by the Prime Minister, Mrs. Theresa May, in her Lancaster House speech.

"It is especially important to achieve control of our laws, control immigration and achieve new trade agreements with other countries. The ERG speaks individually, not with the collective view, but has considerable support across the Parliamentary Party. As Chairman I intend to be helpful, vigorous and supportive towards Government policy of making a success of Brexit.”
