Former UK ambassador thinks Brexit negotiations could descend into 'fist-fighting'

Negotiations to leave the European Union are likely to descend into "name-calling" and "fist-fighting" before any agreement can be found, the UK's former ambassador to the EU has warned.

Ivan Rogers, who quit in January after telling British Prime Minister Theresa May that Brussels diplomats thought it might take 10 years to reach a deal, said there was a "humongous" amount of work to do in what would probably be the country's largest ever negotiation.
