Prince Philip spent a sixth night at King Edward VII’s hospital in London after being admitted last Tuesday as a "precautionary measure" after feeling unwell. HELLO! understands that the Duke walked in unaided and it was not an emergency admission.

William's comments came as he visited a vaccination centre at the King's Lynn Corn Exchange in Norfolk on Monday to pay tribute to the incredible efforts and dedication of the staff involved in the Covid-19 vaccine rollout.
The Duke spoke with NHS staff and volunteers about their experiences, as well as meeting with a number of people receiving their vaccine that day.
William, who contracted the virus himself last April, asked vaccinator Debbie Rudd, 50, whether the patients were nervous, adding: "I'd be at the front of the queue if I could, just to prove that it's OK, but I have to wait my turn."
He later told staff: "Honestly, you guys have overcome every challenge that's been thrown at you. Brilliant work."
Cambridgeshire Community Services NHS Trust delivers the four large-scale vaccination centres across Cambridgeshire, Peterborough, Norfolk and Waveney, alongside a number of GP and pharmacy-led sites. The vaccination centre at the Corn Exchange King's Lynn opened on 1 February and has delivered thousands of vaccines every week since.
The Queen, the Duke of Edinburgh, the Prince of Wales and the Duchess of Cornwall have all received their vaccination.
William and his wife Kate are currently staying at their Norfolk home, Anmer Hall, with their three children, Prince George, Princess Charlotte and Prince Louis, during England's third lockdown.
