The German Chancellor, Angela Merkel, has told Germany's Bild Zeitung newspaper that the enlarged 27-member EU needs a new constitution to streamline decision-making.

Meanwhile in Rome, where the treaty that led to the EU was signed, European Commission president Jose Manuel Barroso said European politicians had to convince citizens that the EU was the best answer to 21st-Century challenges such as globalisation and sustainable growth.

Berliners are being invited to a party thrown by the EU to celebrate the 50th anniversary of the Treaty of Rome.

A highlight will be an all-night clubbing extravaganza, in which ravers can hop between 35 Berlin nightclubs for an EU-subsidised 12 euros (£8).

There will also be free bratwurst and beer, and museums will open all night.
