The group of 29 asked the European Parliament (EP) to provide information relating to the Euro MPs expenditure during the past four years. The EP said it didn't keep the information and wanted to protect the privacy of Euro MPs. It also argued that releasing the documents would be too much work.

It's believed the EP forks out nearly 40 million euros in expenses to Euro MPs. The expenses come in addition to the Euro MPs' monthly salary of 8,000 euros.
