EU summit: Leaders meet for Rome anniversary

Pope Francis welcomed the leaders to the Vatican on the eve of the summit.

In a speech, he said that all bodies risk dying if they do not look ahead, and thus urged the EU to approach the future with renewed vigour.

He also warned against "false forms of security" promised by populists who want to wall themselves off, and instead urged greater solidarity.

The original Treaty of Rome launched the European Economic Community, the EU's forerunner.

It was signed by six countries: Belgium, France, Italy, Luxembourg, the Netherlands and West Germany.
