British Prime Minister Boris Johnson will set out a five-tier warning system for the coronavirus later today when he outlines the government’s roadmap for gradually easing lockdown measures that have shut down much of the UK economy for nearly seven weeks, Reuters reported.

The government’s flagship “stay at home” slogan will be replaced with “stay alert”, a decision that drew criticism from opposition parties for being too ambiguous.

“We need to have a broader message because we want to slowly and cautiously restart the economy and the country,” housing minister Robert Jenrick told Sky News, adding that Johnson would be setting out the roadmap for “the weeks and months ahead”.
