Rudy Giuliani was so drunk on election night that former President Donald Trump's aides were concerned he'd accidentally smash valuable White House china, presidential biographer Michael Wolff told MSNBC. Wolff described how on the night of November 3, 2020, the former New York City mayor was struggling to maintain his balance while trying to convince others that Trump had won re-election. At one point, he was pulled aside into the White House's china room by several aides of the former president, Raw Story reported. "And at that moment, Rudy was incredibly drunk, weaving this way and that way," Wolff told MSNBC host Andrea Mitchell on Friday afternoon.

"But they were also concerned that he was going to break the china."

 More than 600,000 people using the NHS Covid-19 app in England and Wales were sent self-isolation alerts in the week between 8 and 15 July.

Data shows 618,903 alerts were sent - a 17% rise from the previous week.

There are complaints from businesses that the alerts are causing serious staff shortages and affecting services.

However some fully-vaccinated key workers will be exempt from self-isolating if they are pinged by the app as a close contact of a positive case.

Business secretary Kwasi Kwarteng told the BBC a “very narrow” list of jobs would be released today.

Self-isolation for all fully-vaccinated people pinged by the app as close contacts is due to be scrapped by 16 August, although there are calls for this deadline to be brought forward.

The app alert is advisory only and not enforceable by law, unlike a phone call from the Test and Trace team.

• Covid app settings changing to send fewer alerts
• NHS Covid app: Should it stay or should it go?
• What are the self-isolation rules if I'm fully vaccinated?

"If you are pinged, you should self-isolate. I know it poses challenges, and we are seeing reports of shortages which we are monitoring, but the rules are clear and I think they should be followed," Mr Kwarteng told the Today Programme on BBC Radio 4.

Latest government figures show there are a further 44,104 daily coronavirus cases in the UK, with 73 coronavirus-related deaths.

Prime Minister Boris Johnson warned cases could rise even more this week, as most legal restrictions have ended in England.

His spokesman said that the app was doing "what it's designed to do".

"We're aware of the impact on some industries and services and working closely with them particularly food and supermarkets….we have a robust and resilient food supply chain."
