The British Parliament is to consider a bill paving the way for a referendum on Britain's membership of the European Union.
Eurosceptic James Wharton (Conservative) is to put forward a bill outlining the terms of a referendum to be held by 2017.
Mr Wharton's bill will receive its first reading in the House of Commons on 19 June when it is presented with other bills in Thursday's ballot.
The earliest date he can request a debate on the floor of the House is 5 July.
The draft bill would require a referendum by the end of 2017 on the question: "Do you think that the United Kingdom should remain a member of the European Union?"
The BBC reports it is likely to be opposed by the Liberal Democrats and Labour.
