The palace said Philip didn’t travel by ambulance and it wasn’t an emergency admission. He is expected to be in hospital for a few days.

Philip, also known as the Duke of Edinburgh, married Elizabeth in 1947 and is the longest-serving consort in British history.

Philip enjoyed robust health well into old age, but has had a number of health issues in recent years. He stopped attending public engagements in 2017.

In 2011, he was rushed to a hospital by helicopter from Sandringham after suffering chest pains and treated for a blocked coronary artery.

In 2017 he spent two nights in the King Edward VII hospital and was hospitalized for 10 days in 2018 for a hip replacement.
