Tory Eurosceptics' Greek cash fearspublished at 09:20
In other news, Conservative Eurosceptics have expressed their fear the UK may have to contribute to an emergency fund to pay for part of the Greek bailout, despite a 2010 political agreement ruling it out.
A source close to Chancellor George Osborne has said the government is "immovable" on the issue and will not contribute to eurozone bailouts.
But Tory MP Steve Baker said Westminster may be unable to stop UK taxpayers' money being spent.
The final decision may be made by EU states under a qualified majority.
