Donald Trump and First Lady Melania Trump have tested positive for coronavirus

The US President was self-isolating with his wife while waiting for Covid-19 test results after one of his closest aides became infected.

In a tweet, he said both he and Mrs Trump were awaiting results after Hope Hicks tested positive.

Now, he has tweeted to confirm he and his wife have tested positive.

He wrote: "Tonight, @FLOTUS and I tested positive for COVID-19.

"We will begin our quarantine and recovery process immediately.

"We will get through this TOGETHER!

His Covid-19 diagnosis is the latest among world leaders, with Prime Minister Boris Johnson admitted to intensive care after contracting the disease and the EU’s chief Brexit negotiator Michel Barnier also falling ill.

The developments came as SNP MP Margaret Ferrier admitted breaking self-isolation rules by traveling to Parliament after experiencing symptoms and then taking a train to Scotland having tested positive.

Her party swiftly suspended her after the disclosure but leaders Nicola Sturgeon and Ian Blackford were facing questions over what they knew and when amid anger at the MP’s actions.

Earlier in the day, Health Secretary Matt Hancock said there were “early signs” that new restrictions imposed in the past month were beginning to have an impact.
