Boris Johnson has said that Britain needs a to leave the Customs Union with "speed and efficiency" after Brexit .

The UK has committed to retaining membership of a temporary customs union after Brexit to reduce barriers to trade. However the Government has refused to say how long it will last.

Mr Johnson told BBC Radio 4's Today programme that businesses want the UK to leave the Customs Union with "speed and efficiency".

He said: "There's the customs union transition period, where there's a discussion about how long that will go - one, two, three years, how you would run that.

"My view is that we should get on. What business would want us to achieve is speed and efficiency."

He also appeared to concede that the UK could pay some form of Brexit divorce bill after previously saying that the European Commission could "go whistle" for sums as large as £100billion. He said "we are bill-paying people", adding that the UK will meet its "legal obligations".
