Leaders of Germany, France and Italy said EU was '

Plans for 'a closer European Union' have been branded an attempt to create a 'European superstate'.

Germany's foreign minister Frank-Walter Steinmeier and his French counterpart Jean-Marc Ayrault today presented a proposal for closer EU integration based on three key areas - internal and external security, the migrant crisis, and economic cooperation.

But the plans have been described as an 'ultimatum' in Poland, with claims it would mean countries transfer their armies, economic systems and border controls to the EU.

Zaoralek added that the four eastern members had reservations about the proposed common security policy.

Eastern members have become increasingly jittery on security issues since Moscow used so-called "hybrid warfare", or undeclared covert tactics - to annex the Crimean peninsula from Ukraine in 2014.

Poland's public TVP described the Franco-German proposal as an "ultimatum" designed to create a European "superstate dominated by large nations."

Ayrault described the Franco-German proposal as a "contribution", adding that there would be "others".

According to the Daily Express, the nine-page report has 'outraged' its foreign minister Witold Waszczykowski.

He said: 'This is not a good solution, of course, because from the time the EU was invented a lot has changed.

'The mood in European societies is different. Europe and our voters do not want to give the Union over into the hands of technocrats.'

The Express reports the document says France and Germany will 'strive for a political union in Europe' and 'invite the next Europeans to participate'.

It comes after the UK voted to leave the EU in a landmark referendum last week, causing shockwaves across Europe.

The result has prompted right-wing European parties in France and Eastern Europe to suggest similar votes, with the EU criticised for its 'federalism' and European Commission President Jean-Claude Juncker blamed for Brexit within the organisation.

In a joint statement tonight the leaders of Germany, France and Italy say the European Union 'must dedicate itself to the worries expressed by its citizens.'

In their statement Monday, the three leaders said that the EU is a success and that the bloc is indispensable in securing 'the economic and social progress for our people, and to assert Europe's role in the world.'

But German Chancellor Angela Merkel, French President Hollande and Italian Premier Matteo Renzi acknowledged that the EU can only advance if it is supported by its people.

The union and especially its policy makers in Brussels have often been criticized for being detached from ordinary people's worries - a sentiment that has led to a strengthening of anti-EU movements in several of its member states.

Meanwhile Poland would like to see Britain hold a second in-out referendum on its membership of the EU, the country's ruling party leader said today.

Jaroslaw Kaczynski, the powerful leader of Poland's conservative Law and Justice (PiS) party, said the bloc would have to 'radically change' in order for Britons to want to return.

The former Prime Minister said that the 'idea for today... foresees efforts aimed at making Britain return' which included a second referendum.

But, he cautioned, the 'EU would have to radically change' for this scenario to be feasible.

Meanwhile the result continues to cause deep divisions within the UK, with departing Prime Minister David Cameron and Chancellor George Osborne criticised for a lack of leadership, while Leave campaign figurehead Boris Johnson has also come under fire for 'backtracking' on arguments he made in favour of Brexit.
