LONDON (Reuters) - Prince Philip, the husband of Britain's Queen Elizabeth, is "comfortable and in good spirits" but will cease public engagements for two months after an operation on his abdomen, Buckingham Palace said on Monday.

He will remain in hospital for up to two weeks and take "a period of convalescence of approximately two months", the palace said in a statement, confirming that the Prince was expected to resume public engagements in the autumn.

Prince Philip was admitted to the London Clinic on Friday, where he underwent "an exploratory operation following abdominal investigations".

The Prince, who has been consort to the Queen for the last 65 years, marked his 92nd birthday in hospital on Monday, receiving a visit from his youngest son, Prince Edward.

The Queen was due to visit her husband in the evening, media reported.
