British Health Secretary Sajid Javid has tested positive for Covid-19 and is suffering "very mild" symptoms.
Mr Javid, who has received both vaccine doses, said on Saturday (Jul 17) night a PCR test had confirmed a positive result he received by lateral flow test.
He said he would continue to self-isolate and work from home.
Meanwhile, England's deputy chief medical officer, Prof Jonathan Van-Tam, has warned of a "bumpy winter" ahead.
It comes as the UK recorded more than 50,000 daily cases for the second day running, days before almost all legal restrictions on social contact are lifted in England on Monday.
There were 54,674 cases – following 51,870 new cases on Friday – with 41 deaths within 28 days of a positive coronavirus test.
The last time cases exceeded 50,000 was in mid-January.
