Some smaller countries, like Singapore, have no scheduled domestic flights.[citation needed] Medium-sized countries like the Netherlands have very few domestic flights; most of them are merely a leg between small regional airports such as Groningen Airport Eelde, Maastricht Aachen Airport and Rotterdam The Hague Airport to pick up passengers from various parts of the country before proceeding to international destinations.[3] In June 2013, Dutch MP Liesbeth van Tongeren (GreenLeft, previously Greenpeace Netherlands director) proposed to prohibit domestic flights in the Netherlands with the argument that they are needlessly inefficient, polluting and expensive, but Environment Secretary Wilma Mansveld (Labour Party) said such a ban would violate EU regulations that allow airlines to fly domestically.[3]
