Boris Johnson has said schools and non-essential shops will remain shut in England until at least June because the coronavirus transmission rate is still too high to significantly ease the lockdown.

But the Prime Minister said people who cannot work from home should be "actively encouraged" to return to their jobs from Monday and granted unlimited exercise in England from Wednesday.

Mr Johnson outlined "the first sketch of a road map", with a new alert system to determine when aspects of the economy and social lives can be restarted as he tries to limit the damage.

Here are the key points

A new Covid Alert System is being set up determined mainly by the reinfection rate and the number of cases.

The alert levels will be one to five and the higher the level, the tougher social distancing measures will have to be. The PM said the UK had been in Level Four but "we are now in a position to begin to move in steps to Level Three".

From today, people who cannot work from home are being actively encouraged to go to work instead of being told to only go if they must.

But they should avoid public transport if at all possible.

From Wednesday, people are being encouraged to take unlimited amounts of outdoor exercise and even play sports, but only with members of their household.

Visiting and sunbathing in local parks will also be allowed as will driving to other destinations.

But social distancing rules will still have to be obeyed with bigger fines for those who break them.

Schools may begin to reopen by June 1 at the earliest along with the phased reopening of shops.

And at least some pubs, restaurants, hotels and other public places could begin to reopen in July at the earliest "if and only if the numbers support it".
