Piers Morgan has slammed Boris Johnson's speech this evening as 'disingenuous' and a 'total waste of time'.
The Prime Minister said that the coronavirus was “the most vicious threat this country has faced in my lifetime”.
And he added: "It’s a fact that by adopting those measures we prevented country from being engulfed by what could have been a catastrophe in which the reasonable worst case scenario was half million fatalities".
But Mr Morgan was less than impressed.
The GMB presenter tweeted: "The Prime Minister changed UK strategy after he was told the herd immunity policy he’d been pursuing for weeks would lead to 500k deaths.
"How many died unnecessarily before he U-turned to the way everyone else was already doing it?"
He added once the speech was over: "So nothing’s really changed then. Total waste of time."
In the speech the Prime Minister urged people who cannot work from home to go to work, but avoid public transport.
He said there would be new guidance for business to help with social distancing but little detail was put forward.
He also said that primary schools could begin to reopen from next month in 'phases'.
From Wednesday people in England can spend as much time as they like outdoors.
Piers was not impressed with the lack of clarity: "Why can I now walk 2 metres away from any random strangers all day long - but not do the same with my family and friends?".
He also wrote: "So, the Prime Minister is urging millions of non-essential workers to go out to work - but also telling people we still can’t see family or friends even if we maintain the same social distancing rules as non-essential workers at work? Makes no sense."
The GMB presenter will interview Scotland First Minister on GMB tomorrow as he returns to work following a coronavirus scare (he tested negative).
Nicola Sturgeon slammed the UK Government's decision to change slogans and said the first she heard of it was when then Sunday newspapers broke the story late on Saturday evening.
The politician and presenter are in rare agreement over the new 'stay alert' messaging.
At lunchtime on Sunday Morgan wrote on Twitter: "If you have to issue a lengthy statement ‘explaining’ what your new slogan means, then the slogan is useless."
He added: "This is just vague imprecise bulls***, Prime Minister & is already causing massive confusion.
"Sort your messaging out ASAP or more people will unnecessarily die."
Shadow health secretary Jonathan Ashworth tweeted: "Lack of clarity tonight from Boris Johnson. I have always warned this virus thrives on ambiguity.
"Many tonight will be asking whether they are being asked to go back to work or not tomorrow, what safety measures will be in place, how will they get to work."
Mayor of London Sadiq Khan said: "I want to be as clear as possible: social distancing measures are still in place. Lockdown hasn't been lifted and we all still need to play our part in stopping the spread of Covid-19.
"You must still stay at home as much as possible and keep a safe two-metre distance from other people at all times when you are out. Everyone must continue to work from home if they possibly can.
"You must not use public transport for any unnecessary journeys. If you really have to travel, please avoid rush hour.
"We still have a long way to go to defeat this virus and we have not returned to life as it was before.
"The Government has set out a gradual approach to bring the UK out of the current lockdown, carefully monitoring the impact at each stage. This is essential for avoiding a disastrous second peak that could overwhelm our NHS."
