It has also emerged that a COBR meeting to thrash out the approach across the UK to rising cases of the virus will be held tomorrow, after this was requested by the Scottish Government.
Mr Johnson also spoke separately with Welsh First Minister Mark Drakeford and Northern Ireland First Minister Arlene Foster this afternoon.
“During these calls, the Prime Minister made clear that the rising infection rates are a cause for great concern, which he is taking very seriously," a Downing Street spokesperson said afterwards.
“He reiterated his unwavering commitment to working with the devolved administrations as we continue to tackle the virus.
"They all agreed to act with a united approach, as much as possible, in the days and weeks ahead.
“The Prime Minister invited the First Ministers and the deputy First Minister to attend a COBR tomorrow to discuss next steps for the country.”
