What does Sir Ivan Rogers' resignation mean for Brexit?
Britain's outgoing ambassador to the EU, Sir Ivan Rogers, has strongly criticised the government's preparations for Brexit. In a resignation letter obtained by the BBC, he urged his colleagues to continue to challenge what he called "muddled thinking" and "ill-founded arguments". It means Theresa May will need to replace a seasoned and experienced diplomat with someone equally intelligent, familiar with the workings of the EU and capable of getting the "best possible deal" the government keeps promising, but who doesn't have any views.
