The diplomat whose warning about Brexit made international headlines has resigned his role as the UK ambassador to the European Union.
Sir Ivan Rogers, who had held the role since November 2013, caused fury among Leave campaigners last month after his warning to the government that an EU trade deal could take a decade to finalise.
This projection directly contradicts the claims made during and since the Brexit referendum by Leave campaigners, who argue that both sides will want to conclude a trade deal quickly as it is in both Britain and the EU's interests.
Rogers' resignation has reportedly been greated with surprise at Downing Street, coming as it does just weeks ahead of the triggering of Article 50 - which will begin Britain's formal separation from the EU.
The news has sparked a flurry of interest and comment among Britain's Brexit commentators. James McGrory, director of pro-Remain thinktank Open Britain and a regular contributor to talkRADIO, tweeted that Rogers' decision was bad for the country, saying "you want your best negotiators around the table and Sir Ivan Rogers is one of Britain's best."
