The leaflet is expected to set out the ‘key facts’ relating to a No Deal Brexit and will show there is ‘nothing to fear’ from such a departure.

It will detail advice on travel arrangements, medicine and food supplies, and warn against stockpiling, according to The Sun.

There will also be a No Deal website launched where people will be able to go to answer any questions they have about how they could be affected.

Mr Johnson’s Brexit ‘war cabinet’ will meet for the first time tomorrow while Mr Gove, the minister responsible for contingency planning, has reportedly been told to hold daily progress meetings with civil servants and advisers.
