The Duke of Edinburgh has been transferred to St Bartholomew's Hospital to treat an infection - after 13 nights at another London hospital, Buckingham Palace has said.
Doctors treating Prince Philip, 99, will also undertake testing and observation for a pre-existing heart condition, the palace said.
The duke is responding to treatment and "remains comfortable", the palace said.
He is expected to remain in hospital until at least the end of the week.
Philip, who turns 100 in June, was taken to King Edward VII's hospital in London on 16 February as a precaution after feeling unwell.
