.@DUPleader refers to the 869 Covid in patients in hospital today as an "incredible" figure. Says that's more than double the total from the first wave.

Meanwhile, The Northern Ireland Fire and Rescue Service has become the latest emergency service to warn of the impact of the pandemic on its members.
It said: "Like many organisations we are beginning to feel the impact on our ability to deliver our service.
"However, coping mechanisms have been put in place and are working well thanks to the resilience and hard work of our people."
It expressed confidence it could continue to deliver emergency response to all parts of the country.
The Northern Ireland Ambulance Service (NIAS) has also experienced reduced numbers of staff.
Non-emergency staff have been drafted in to help on the front line but partners from other emergency services have been asked for help.
An NIAS spokesman said: "Even with these additional resources, challenges remain and we are extremely grateful to our colleagues in the other emergency services who have made available a number of staff to assist us at this difficult time."
He added: "These actions will ensure that the clinical expertise of our own frontline staff is optimised in the most effective manner."
More than 100,000 coronavirus vaccinations have been administered to date.
The programme is being stepped up but is dependent on the availability of supplies.
Chief scientific adviser Professor Ian Young said the average number of new cases of coronavirus per day had risen to more than 2,000 a day.
He said that while the number of cases is falling, they remain at a "very high level".
Meanwhile, an additional 63 deaths with Covid-19 have been recorded in the Republic of Ireland.
Another 3,569 cases were confirmed, the Department of Health said.
Chief Medical Officer Dr Tony Holohan said: "We are seeing some early signs of progress with daily cases numbers and positivity rates.
"We can take some hope in them, but we have a long, long way to go.
"In the coming weeks ahead, we will need to draw upon our reserves of resilience from springtime as we can expect to see hospitalisations, admissions to ICU and mortality related to Covid-19 increase day on day."
