Covid: Boris Johnson leads coronavirus briefing on post-lockdown plan and vaccines
Boris Johnson is updating his plans for a strengthened three-tier system of Covid-19 restrictions to replace the national lockdown in England after it ends on December 2.
The prime minister will explain his "Covid Winter Plan" in virtual press conference from Downing Street at 7pm.
Mr Johnson - who is self-isolating - will be speaking alongside Chief Medical Officer Prof Chris Whitty and the Director of the Oxford Vaccine Group Andrew Pollard.
His plan - which he unveiled earlier in the House of Commons - involves a tightening of restrictions in the tiered system, which England will return to once lockdown is over.
There will also be an update on the progress of coronavirus vaccines, after one developed by Oxford University and AstraZeneca was found to be up to 90% effective in stopping people contracting coronavirus and getting seriously ill
The PM may also give some indication of what restrictions may be relaxed over Christmas, with more information expected over the coming days.
