The Government's new "stay alert" slogan for the next stage of the UK's fight against coronavirus has divided opinion.
The "stay at home, protect the NHS, save lives" message that has been drilled into the public for weeks is expected to be dropped for a call to "stay alert, control the virus, save lives".
Boris Johnson is expected to unveil a five-tier warning system during his address to the nation tonight similar to that used for terror attacks, ranging from level one to level five at the most severe, with Britain currently on level four.
The new system will be assessed by a Joint Biosecurity Centre which will be tasked with identifying local spikes of infections.

The Prime Minister is planning to urge workers who cannot do their jobs from home to begin returning to their workplaces while following social-distancing rules.
The new slogan is understood to have been drawn up by Australian strategist Isaac Levido and Ben Guerin, the Conservatives' 2019 election social media strategist.
Social media users flocked to question whether "alert" was too weak a word.
Top-selling Harry Potter author JK Rowling responded immediately saying: “Is Coronavirus sneaking around in a fake moustache and glasses? If we drop our guard, will it slip us a Micky Finn? What the hell is ‘stay alert’ supposed to mean?”
