Covid-19: Brazil virus already in UK ‘not variant of concern’, scientist says
One of two coronavirus variants first detected in Brazil has been found in the UK, says a leading scientist advising the government.
But the version discovered is not the "variant of concern", Prof Wendy Barclay clarified.
The "variant of concern" from Brazil, detected in travellers to Japan, is thought to be more infectious.
It led to travellers from South America and Portugal being banned from entering the UK on Friday.
Prof Wendy Barclay, who is heading a newly-launched project to study the effects of emerging coronavirus mutations called the G2P-UK National Virology Consortium, said: "There are two different types of Brazilian variants and one of them has been detected and one of them has not."
Prof Barclay, who also sits on Nervtag, a committee which advises government on new and emerging respiratory virus threats, said the variant was "probably introduced some time ago" and it "will be being traced very carefully".
Although the variant in the UK is not the one that sparked the travel ban, it has not been made clear whether it is potentially more contagious or not.
She added: "The new Brazilian variant of concern, that was picked up in travellers going to Japan, has not been detected in the UK.
"Other variants that may have originated from Brazil have been previously found."
It comes as a further 1,248 people with coronavirus have died in the UK.
The latest government figures on Thursday also showed another 48,682 new cases had been reported.
Meanwhile, the latest estimate for the reproduction (R) number in the UK - which represents the average number of people that one infected person will pass on a virus to -
is between 1.2 and 1.3.
Last week it was estimated at between 1 and 1.4 by the government's Scientific Advisory Group for Emergencies.
When the figure is above 1, the number of cases increases exponentially.
Despite other variants entering the country since, the Kent variant remains dominant in the UK and is believed to be 30-50% more infectious than the previous form of the virus.
Viruses acquire random changes to their genes constantly as they replicate.
Many are neutral or even hurt the virus's ability to spread, but those that give it an advantage will become more common.
Mutations are being deteced now because enough time has passed for those random changes to take hold.
Even though there is no evidence any of these mutations make the virus more deadly, a virus that infects more people is likely to have a higher death toll.
When the virus gets better at sticking onto and breaking into human cells, in theory someone exposed to the same dose is more likely to become ill.
The use of masks and personal protective equipment, social distancing and hand washing remain the best defences against the virus's spread.
Downing Street said current evidence did not suggest the concerning Brazilian variant affected vaccines or treatment.
Mr Shapps described the travel ban, which came into force at 04:00 GMT on Friday, as a "precautionary" measure.
It covers people who have travelled from or through, Argentina, Brazil, Bolivia, Chile, Colombia, Ecuador, French Guiana, Guyana, Paraguay, Peru, Suriname, Uruguay and Venezuela in the last 10 days.
The ban also applies to Portugal - because of its strong links to Brazil - and the former Portuguese colony of Cape Verde off the coast of west Africa, as well as Panama in central America.
British and Irish citizens and foreign nationals with residence rights are still allowed to return - but must isolate for 10 days.
Also exempt are hauliers who are travelling from Portugal to transport essential goods.

- I've booked May 21st for a trip to Europe - We should have the jab by then - Hopefully won't have to be tested by then.
