European Union leaders will meet in Malta early next year to discuss Europe's future once Britain leaves, as the 60th anniversary of the EU's founding Treaty of Rome approaches.

Malta's EU office tweeted Monday that the informal talks without Britain are planned "to spur momentum for the new idea of Europe." Malta takes over the EU's rotating presidency in the first half of 2017.

The meeting could take place in early February to leave time to prepare the anniversary of the treaty, signed in the Italian capital on March 25, 1957.

EU leaders are meeting without Britain in Slovakia on Friday. All 28 leaders are scheduled to meet in Brussels on October 20-21 and December 15-16.

Britain's decision to leave has plunged the EU into an unprecedented situation.
