London (CNN) The UK government is launching a TV campaign to urge Britons to be ready for a no-deal Brexit, the country's top civil servant said.

Cabinet Secretary Mark Sedwill told a parliamentary committee that the TV spots will be aired in advance of Britain's scheduled departure from the European Union on March 29. They would complement radio advertisements that are already running.

The disclosure came a day after the UK government published an analysis that concluded the country is nowhere near ready to leave the European Union without some sort of transitional deal.

Sedwill denied accusations from members of the Public Administration and Constitutional Affairs Committee that the government had failed to to prepare the country for a no-deal scenario.

"Individuals, citizens and businesses are making their own judgments, the information is available," Sedwill said. "We've been putting it out on the website for several months, that's now been complimented by some radio advertising and we have plans to bring through some television advertising as well. So there is a communications campaign."
