MEPs have reinforced demands for a single European Parliament seat in a bid to end the monthly travelling circus to Strasbourg.
It comes as the European Council ignored treaty obligations to move meetings from Brussels to Luxembourg for three months each year.
Catherine Bearder, an MEP for the South East, has campaigned vigorously for a single seat to save money and cut carbon emissions.
She said: "The Council seems to have let common sense prevail and dumped a number of its trips to hard-to-reach Luxembourg.
"But I am gobsmacked they have been allowed to break their treaty obligations, while the Parliament gets taken court for trying to save money."
EU ministers decided instead of meeting in Luxembourg in April, June and October, it would compress all formal meetings into a single two day session.
Catherine added: "The Council has laid down a marker. These wasteful journeys are an unnecessary waste of taxpayer's money.
"Time spent commuting is time we could be spending on work. So, it is hindering democracy as well."
Around 77 per cent of MEPs support ending the monthly commute to Strasbourg, while 1.27 million EU citizens have signed the One Seat petition.
Since 2009 MEPs have asked for detailed figures financial, environmental and social cost of trips to Strasbourg, but have yet to receive a breakdown.
Catherine attended an event for an update on the singe seat campaign on Tuesday (April 2).
