EU warns of 'serious consequences' if no Brexit deal

Its leaders say they don't want to punish Britain.

"It's not a small event, it is a situation that is grave and exceptional", Barnier said.

The parties should be transparent and tell the truth about what leaving the bloc means, remove uncertainties concerning people, money and borders and negotiate issues in the right order, Barnier said.

But Barnier said the absence of a deal could lead to long queues of trucks at British port city Dover, disruption of flights to and from Britain and a shortage of nuclear fuel for Britain's nuclear power plants.

"At the same time, the PM is right to spell out her vision of a Britain outside the single market - and outside the European Union legal order - but able none the less to continue the trading relationship that is so important for businesses and consumers both sides of the Channel".

Nine months after the United Kingdom voted to leave the European Union (EU), the Brexit process has officially begun. But we must settle the accounts.

"I hope we will be out of the European Union, but we will take part in security cooperation and other forms of cooperation to recognise that while we are leaving the European Union, we are not leaving Europe, we are not giving up on European values", Cameron said.

"The sooner we reach a deal on an orderly withdrawal, the sooner we can prepare for the future relationship", he said, adding that leaving hard divorce issues until the last moment was playing with failure.

The EU is determined to preserve its unity and has said any Brexit deal must not encourage other countries to follow Britain out of the door.

The 60-year-old has one of the toughest jobs of any recent British prime minister: holding Britain together in the face of renewed Scottish independence demands, while conducting arduous talks with 27 other European Union states on finance, trade, security and other complex issues.

"The UK will not be asked to pay for anything they had not previously agreed to", he added.

Foreign Secretary Boris Johnson, writing in the Daily Telegraph, said: "It is our clear desire and intention that we should continue to play a role as one of the indispensable guarantors of peace and stability in our continent".
