Business secretary Alok Sharma has been tested for coronavirus after falling ill.
The business secretary is currently self-isolating at home after becoming ill in Parliament.
BBC reports a spokesman said the MP for Reading West had been tested for coronavirus and had gone home.
Mr Sharma, alongside a handful of ministers, attended Tuesday's cabinet meeting at Downing Street in person.
The business secretary was in the Commons chamber for almost an hour on June 3.
He was leading for the government on the Corporate Insolvency and Governance Bill.
A spokesman said: "Alok Sharma began feeling unwell when in the Chamber delivering the second reading of the Corporate Insolvency and Governance Bill.
"In line with guidance he has been tested for coronavirus and is returning home to self isolate."
Shadow business secretary Ed Miliband passed Mr Sharma a glass of water.
On Twitter, Mr Miliband sent the business secretary his best wishes and said: "Best wishes to @AlokSharma_RDG for a quick recovery. Hope he feels better soon."
It is not currently known whether the business secretary has coronavirus.
On Good Morning Britain, presenter Susanna Reid said he "didn't look terribly well" and stressed everyone hoped he did not have coronavirus.
Guest on the show Andrew Marr said if Mr Sharma does test positive for coronavirus, "it is the end of the face to face Parliament we have seen for a few days".
