As a PR plan it is certainly ambitious, featuring endorsements from world leaders and an interview with Theresa May by David Dimbleby. However, Downing Street insists a leaked “communications grid” supposedly intended to sell a Brexit strategy does not reflect its thinking.

Details of the plan, seen by the Guardian among others, lay out an apparent timetable for the month, from a cabinet meeting on Tuesday to a House of Commons vote on the deal it says will take place on 27 November.

The days between are filled with a list of media events and supportive statements, beginning with a triumphant announcement from the Brexit secretary, Dominic Raab, that the cabinet has agreed a deal.

“The narrative is going to be measured success, that this is good for everyone, but won’t be all champagne corks popping,” the leaked note says.

Among later events in the schedule are a speech by May to the CBI conference, which the leaked planner says would argue the agreement “brings the country back together, now is the time for us all to unite behind it for the good of all our futures etc”.

On the same day, the withdrawal agreement and outline deal on a future relationship with the EU would be put to parliament, with an unnamed set of junior ministers tasked with “doing regional media all day”.

“Government lining up 25 top business voices including [the CBI director general] Carolyn Fairbairn and lots of world leaders eg Japanese PM to tweet support for the deal,” it adds, but does not say whether the Japanese prime minister, Shinzo Abe, has been approached about the proposed arrangement.

The rest of the time before the Commons vote is filled with themed days, including a UK-wide sales pitch, which would see May visit “the north and/or Scotland”, and another day devoted to the economy.

Other days would cover immigration, the NHS and Northern Ireland. The entry for the latter says the aim would be for May to visit Northern Ireland and try to get the support of the Irish prime minister, Leo Varadkar, which the memo misspells as “Varadker”.

A final flurry of efforts would see May supposedly doing an interview with Dimbleby.

A Downing Street source was quick to distance itself from the leaked plan. “The misspelling and childish language in this document should be enough to make clear it doesn’t represent the government’s thinking. You would expect the government to have plans for all situations – to be clear, this isn’t one of them,” they said.
