Liberal Democrat leader Nick Clegg used his closing speech at his party's spring conference to make the case for membership of the EU.
The deputy prime minister acknowledged reform was needed but stressed the UK could not demand changes with "one foot out of the door".
He said his party was the "only party out there explaining the clear benefits of Britain's place in Europe".
