Britain will seek a unique arrangement for it post-Brexit relationship with the European Union, one that will deliver migration controls and a positive trade outcome, a Cabinet meeting at Chequers heard.

At the first Cabinet meeting after the summer break held at the Prime Minister's official country residence Chequers, Theresa May had tasked her colleagues to set out the opportunities that leaving the EU will create in each of their departments.

Speaking to colleagues on Wednesday, May said there would be no second referendum on Britain's withdrawal from the EU and reiterated her pledge that "Brexit means Brexit, and we're going to make a success of it".

She added: "That means there's no second referendum; no attempts to sort of stay in the EU by the back door; that we're actually going to deliver on this."

Cabinet ministers agreed that it is for the Government alone to decide when to trigger Article 50, which will kick off a two-year period of exit negotiations between the UK and the EU, and that there is "no need" for MPs to give their approval in a vote.

Several Cabinet members made it clear that we are leaving the EU but not leaving Europe, with a decisive view that the model we are seeking is one unique to the United Kingdom and not an off-the-shelf solution. This must mean controls on the numbers of people who come to Britain from Europe but also a positive outcome for those who wish to trade goods and services.

Following the day-long session - dubbed a "Brexit brainstorm" by Labour, Mrs May's official spokeswoman said: "Ministers agreed that we should be seizing the opportunity of Brexit to confirm the UK's place as one of the great trading nations in the world, fostering entrepreneurialism and setting out a long-term vision for the country."

The meeting also restated the Government's commitment to "fiscal discipline and living within our means" and agreed on "the vital need to increase productivity and the importance of doing more to foster economic growth and industrial development in regions up and down the country", said the spokeswoman.
