The prime minister will hold a special three-hour meeting to discuss preparations for a Brexit no-deal.
The government is also due to the publication of indications on issues such as mobile roaming charges, driving licenses and passports in case the EU and the UK do not reach an agreement.
Secretary Brexit said that the UK would not pay its financial agreement to the EU in a scenario without agreements.
He said that the government is "stepping up" its emergency plan
Theresa May's proposals, exposed after a summit by Checkers in July, are fiercely opposed by some Conservative MPs and the EU also expressed reservations.
The United Kingdom will leave the EU in March 201
Last month, the government published 24 no-deal documents covering areas such as medicine, finance and agriculture. There have been warnings of additional border documents and additional credit card costs for Britons visiting the EU.
Writing in the Daily Telegraph, Secretary Brexit Dominic Raab said Thursday's 28 documents "range from protecting consumers from mobile phone roaming charges to meeting environmental standards".
Additional costs for people who use their phones in another EU country were scrapped in June 2017. But the EU regulation banning them will not automatically be part of UK law after Brexit.
Ms. May said the UK will no longer be part of the "digital single market" of the EU after Brexit.
In theory this means that the UK mobile operators, if they wish, could reintroduce the charges that could make the use of a mobile phone in another EU country expensive.
However, last month major operators told the BBC not to have
"Nonsense" and "scaremongering"
Raab said that the non-agreement plans were "not something we want to implement".
"No one should pretend that no agreement" would be simple, "he said
" There would be risks and some short-term interruptions: additional controls at EU borders would lead to delays in companies ".  And trade with the EU on the terms of the World Trade Organization – a result supported by a group of Brexiteers in a report this week – would be "inferior" to current agreements, he said.  But Raab also criticized those who called "political alarmism" for failing to reach an agreement.
"It is absurd to say that UK supermarkets would miss food," he said, adding that people should not be frightened by the government's request to the pharmaceutical companies to accumulate supplies of extra medicines.
Other non-agreement publications are expected in the coming weeks.
