Prince Philip admitted to London hospital, Buckingham Palace says

Prince Philip, the 96-year-old Duke of Edinburgh and husband to Queen Elizabeth II, has been admitted to the hospital as a "precautionary measure," the Associated Press reported Wednesday, citing information from Buckingham Palace. He was admitted to London's King Edward VII Hospital on Tuesday night, the AP reported.

The palace confirmed to the BBC on Wednesday that Philip is being treated for an infection related to a pre-existing condition but is "up and about and in good spirits." According to the AP, Philip has had past health issues relating to his heart.

In May, Philip announced that he would retire from his royal duties this year and would no longer accept new invitations, although he would "still choose to attend certain public events from time to time," a spokesperson said, according to the BBC.

His hospitalization means he will not attend the queen's address of British Parliament, which is scheduled to take place today. Prince Charles will attend in his place, according to the AP.
