The number of COVID-19 deaths in the UK have surpassed 5,000 after the country recorded an increase of 439 in a day.

The UK has confirmed more than 51,000 cases as the disease continues to spread across the globe.

The report on the latest figures comes after Prime Minister Boris Johnson said he was in good spirits after spending the night in hospital with COVID-19.

The 55-year-old was admitted at the St Thomas’ Hospital in London on Sunday evening with "persistent symptoms", including a temperature and a cough.

"Last night, on the advice of my doctor, I went into hospital for some routine tests as I'm still experiencing coronavirus symptoms. I'm in good spirits and keeping in touch with my team, as we work together to fight this virus and keep everyone safe," Johnson wrote on Twitter.

The UK is one of the most affected countries in Europe, with only Spain, Italy, Germany and France having recorded more COVID-19 cases in the continent.

Johnson also called upon fellow UK citizens to remain at home in efforts to curb further spread of COVID-19.

"I'd like to say thank you to all the brilliant NHS staff taking care of me and others in this difficult time. You are the best of Britain," he said. "Stay safe everyone, and please remember to stay at home to protect the NHS and save lives."
