Theresa May has ordered every Cabinet minister to come up with a personal blueprint for Brexit amid concerns that civil servants are trying to frustrate Britain’s departure from the European Union.

The Prime Minister will demand action plans from each colleague about how their department can make Brexit work at a meeting at Chequers, her country retreat, this week.

Mrs May has challenged each minister – more than three quarters of whom campaigned for Britain to stay in the EU – to identify Brexit opportunities in their areas of responsibility.

It comes as senior government sources privately complained that pro-EU civil servants who are jealous of the new department are trying to frustrate the work of Brexit ministers. One senior insider said civil servants were “miffed” at having to help take the UK out of the EU, adding: “A lot of these people are institutionally wedded to the status quo.”
