Britain’s 98-year-old Prince Philip left the hospital on Tuesday after a four-night stay .
Britain’s Press Association reports that Philip did not respond to photographers as he got into the vehicles.
Images broadcast by British media showed Queen Elizabeth II’s husband, dressed in a suit, taking a few steps and being helped into an SUV vehicle before being whisked away.
Multiple police stood guard around the hospital as well as royal protection officers.
According to AFP the Duke of Edinburgh was now expected to join the queen at Sandringham, the central England country retreat where the royal family traditionally spends Christmas.
Philip was admitted to London’s King Edward VII hospital on Friday.
Buckingham Palace said it was for “observation and treatment in relation to a pre-existing condition”, adding that it was a “precautionary measure”.
The duke was reportedly flown there by helicopter from the royal Sandringham estate in eastern England, where he has been based since retiring from public duties in 2017.
