The European parliament has two seats in Europe; Brussels and Strasbourg.
Since years, every month the parliament picks up its bags and moves from Brussels to Strasbourg. There it stays for a week and goes back to Brussels. This is costing the European taxpayers €200.000.000 a year (direct cost). The indirect cost due to inefficiency is not included.
If you think is ludicrous go to the site http://www.oneseat.eu and support the petition for one seat in Europe.
