The UK is "at or close to the bottom" of coronavirus levels, according to England's deputy chief medical officer.

Speaking at a Downing Street COVID briefing, Professor Jonathan Van-Tam said: "We are really in very low levels that are comparable to where we were in September last year.

"We are running as a typical seven-day average at just over 2,000 people testing positive per day.

"My sense is that probably we are at or close to the bottom at the moment in terms of this level of disease in the UK."

But he also warned of "twists and turns ahead" and said he anticipated "some degree of bumpiness" probably in the autumn and winter.

The UK government has announced it has secured another 60 million doses of the Pfizer vaccine to use as booster jabs to protect the country's progress ahead of the colder months.

Prof Van-Tam said the modeling suggested there will be a third wave in the UK but it "may be just a third upsurge and much less significant".
