British Euro MPs want the UK government to back them in a dispute with France over the number of European Parliament sessions held in Strasbourg.
France insists that MEPs must stick to 12 Strasbourg sessions per year, as required by the EU's Lisbon Treaty.
But a majority of MEPs voted in March to squeeze two sessions into one week, to reduce the cost of shuttling from Brussels to Strasbourg.
France objected and has asked the EU's top court to overrule the vote.
The BBC reports the Strasbourg shuttle is estimated to cost 203 million euros ($US290 million) per year. British MEPs call it a ''travelling circus''.
