Britain has the option of using martial law to quell civil disorder that might ensue under a no-deal Brexit, but that is not the focus of the government's attention, Health Minister Matt Hancock said Sunday.

The Sunday Times cited unnamed officials as saying the government has been examining the powers at its disposal if a no-deal Brexit results in civil disobedience, including martial law, curfews and the use of the army to quell rioting.

Asked by the BBC's Andrew Marr if the government is considering the possibility of martial law, Hancock said "Not specifically, no."

Hancock then added: "It remains on the statute book but it isn't the focus of our attention."

Britain is set to leave the European Union on March 29, but the country's lawmakers remain far from agreeing a divorce deal, leaving open the default possibility of a disorderly Brexit.

Officials have been discussing the practicalities of implementing the Civil Contingencies Act 2004, which will allow the government to make any appropriate provisions to protect human life, health, safety and supplies, the Sunday Times said.

"The overriding theme in all the no-deal planning is civil disobedience and the fear that it will lead to death in the event of food and medical shortages," a source told the newspaper.

Hancock said the pharmaceutical industry is doing everything it can to prevent shortages of medicines resulting from any delays at borders resulting from a no-deal Brexit.
