Boris Johnson is set to announce what lockdown easing will look like on June 21 as the government looks ahead to the next stage in the coronavirus roadmap.

The Prime Minister will update the public on June 14 in order to give businesses enough time to prepare for any planned changes.

It was previously reported that the government had drawn up a list of back-up options if the Prime Minister decides he has to delay stage four of the roadmap out of lockdown.

Mirror Online reported that the government may be scrapping some or all of the plans for a return to normal on June 21.

So far, lockdown easing in England has followed the government's proposed dates, with indoor hospitality reopening on May 17.

Concerns regarding the Delta variant, first discovered in India, have thrown the government's roadmap into doubt, with some questioning whether the 'variant of concern' may delay further lockdown easing.

Under the government's initial roadmap plans, Stage 4 on June 21 would mean the removal of social distancing rules and work from home guidance, the removal of all limits on social contact and the reopening of all venues that were unable to return as part of Stage 3, which includes nightclubs.

Large weddings and other events would also be able to take place without restrictions.

How will the government decide whether to unlock fully on June 21?

Officials are analysing the data to see whether it is safe to ease restrictions further.

Under the roadmap, four key tests must be met before the next step can go ahead.

They are:

- That the vaccine deployment programme continues successfully

- That evidence shows jabs are sufficiently effective in reducing hospitalisations and deaths in those vaccinated

- That infection rates do not risk a surge in hospitalisations which puts unsustainable pressure on the NHS

- That the Government’s assessment of the risks is not fundamentally changed by new variants of concern

We took a look at each of the factors the government will be considering in any decisions around lockdown easing.

Vaccine deployment

According to the UK Covid19 Vaccine Tracker, the predicted update as of June 8 forecasts that all priority groups will have received two doses by June 20.

The forecast also predicts all adults will have received a first dose by July 13 and that all adults will have both doses by September 5.

These predictions are based on current trends, supply, and second doses debt.

Using data from Public Health England, which was update on June 8, the Vaccine Tracker also suggests the government's target of 53 million people vaccinated with their first dose by July 31 could be achieved up to 18 days early on July 13.

More than 41 million people have now received their first dose of the vaccine, with more than 29 million second doses administered (as of June 8).

Hospitalisations and deaths

According to the Office for National Statistics (ONS) hospital admissions of COVID-19-confirmed patients in England have remained below 1 per 100,000 in the four weeks up to 30 May 2021.

There was, however, a slight increase in the most recent week. Hospital admission rates increased in the North West, East of England and East Midlands, but decreased in the West Midlands. Just over 1,000 people were admitted to hospital in the past week

There were 60 deaths involving coronavirus registered in the last seven days.
