Theresa May has written to officials that no-deal preparations need to be resumed in October despite a new deadline for Britain to leave the European Union.
An e-mail from the Guardian shows that the Prime Minister has told government officials that plans for a fall out of the EU are necessary and will continue to be signed by permanent secretaries.
There is criticism of the May administration for wasting money after being told in a leaked e-mail to Sky News that "no-deal" plans have been "abolished".
In an e-mail sent to the public service on Monday, May clarified this point and wrote that some no-deal plans would continue. Leading officials, including Cabinet Secretary Mark Sedwill, would decide which plans could be withdrawn, the Prime Minister said.
"The preparations, which are specifically designed for leaving the EU without consultation, are rightly directed by the Cabinet Secretary and your own permanent secretaries on further planning. The necessary preparations for a no-deal outcome need to be continued, but with well-timed schedules in the light of our agreed extension, "wrote May.
On Friday it turned out that the government had ceased Operation Yellowhammer, its contingency plan, following the postponement of Britain's exit from the EU due to the worst-case scenario resulting from a no-deal Brexit.
Some 6,000 officials have prepared for a no-deal Brexit, estimated to cost £ 1.5bn.
The decision followed an agreement between the EU Council and the United Kingdom to postpone the Brexit deadline to 31 October. However, there were conflicting reports about how far no-deal planning would continue.
Employees seconded from elsewhere now return to their normal duties, but no clear role is seen for an estimated 4,500 new hires. Approximately 16,000 officials were hired or recruited to fill posts related to the Brexit.
In the e-mail, May also praised the civil service for his work on the Brexit preparations. "I hope you can take a well-earned break in the Easter holidays," she said.
Mai's letter was welcomed by the FDA union, which represents high-ranking officials. Dave Penman, the head of the FDA, said, "Too many times she and her ministers have been silent because members of her own party have tried to undermine the impartiality and integrity of the civil service.
"I hope this means a change in the Prime Minister's approach and that the officials to whom she has praised today can rely on her to defend her in the future," he said.
