A UK business leader has called for continued membership of the EU.
John Cridland, Director General of the Confederation of British Industry, said:
"We have looked beyond the political rhetoric to examine the pros and cons of EU membership and British business is unequivocal - the Single Market is fundamental to our future.
"We are better off in a reformed EU than outside with no influence. Each year, membership is worth £3,000 to every household in this country.
"But the EU isn't perfect and there is a growing unease about the creeping extension of EU authority. Europe has to become more open, competitive and outward-looking if we are to grow and create opportunities and jobs for all our citizens.
"Contrary to popular myth, the UK is influential in the corridors of Brussels and will still be as long as we play our cards right. The Single Market is a great British success story and the best way for us to remain a leader on the world stage is from within the EU."
Staying in the European Union is "overwhelmingly" in Britain's interest, although reforms are urgently needed, business leaders have said.
The Confederation of British Industry has highlighted research showing that EU membership was worth between £62 billion and £78 billion, around 4-5% of the UK's total economic output.
But the business group, which holds its national conference in London today, called for a number of reforms, including removing barriers to e-commerce, becoming more outward-looking and re-focusing the work of EU commissioners.

The failure to allow prisoners to vote sets a "very bad example" and will make the life of jail staff more difficult, the Chief Inspector of Prisons has warned.
Nick Hardwick admitted few prisoners were interested in taking part, but denying them the opportunity to vote would send out the wrong message:
"I think the judgment's been made and what would set a bad example would be if we said to prisoners 'We don't like that judgment, therefore we aren't going to do it'.
Mr Hardwick suggested there was an argument for withholding the vote from prisoners serving long sentences for "heinous" crimes, but to grant those serving shorter sentences the vote.
David Cameron has hailed the Supreme Court's ruling on prisoner voting as a "great victory for common sense".
The Supreme Court ruled that convicted murderers Peter Chester and George McGeoch were not entitled to vote while in prison.
The Supreme Court judgment on prisoner voting is a great victory for common sense.
Convicted murderers Peter Chester and George McGeoch have lost a Supreme Court battle today over the right to vote while in jail.
David Cameron previously said the idea of giving prisoners the vote made him feel "physically ill".
The Supreme Court will today rule whether prisoners will have the right to vote in the next election.
Speaking in November 2010, Mr Cameron said: "It makes me physically ill to even contemplate giving the vote to anyone who is in prison. Frankly when people commit a crime and go to prison they should lose their rights including the right to vote."
However, the Attorney General Dominic Grieve has warned that it would be a "serious matter" if Britain defied the ruling and could lead to a significant amount of compensation having to be paid out.
