The heads of the 27 EU member states at the informal summit in Bratislava agreed to present in six months a detailed plan for development of the block based on Britain's withdrawing from the Union.
"In Bratislava, we have agreed n the coming months to offer our citizens our vision of an attractive model of the European Union, to which they can trust and which they can support", - stated in the so-called Bratislava Declaration, adopted at the summit.
It is expected that EU development road map will be adopted at the bloc leaders' meeting in March in Rome next year.
"Despite the fact that one country decided to withdraw from the EU structure, the European Union is indispensable for us", - said in the text of the declaration.
According to German Chancellor Angela Merkel, special attention in the road map will be given to the problem of curbing illegal migration and strengthening cooperation in the field of security.
"We very specifically discussed what should be done to solve problems such as migration ... We all have to make compromises," - said Merkel.
President of the European Council Donald Tusk stressed that one of the main objectives of the leaders of the EU countries - to prevent the uncontrolled flow of migrants, which was observed in the past year.
