Brexit talks uncertainty 'leaves 45% chance of no deal', says article 50 author

Lord Kerr, who helped draft EU legislation, says uncertainty over who will lead negotiations for UK is 'very real problem'

Uncertainty about who will lead Brexit divorce talks for Britain is a "very real problem", the diplomat who helped draft article 50 has said, as he warned the UK faces a 45% chance of crashing out of the EU with no deal.

John Kerr, a crossbench peer who served as the UK's ambassador to the EU, said there was "a very real problem in the United Kingdom ... that it is not clear who the negotiators are going to be".
