Prince Philip was admitted to a medical centre in Scotland on Wednesday (15Aug12) with a recurrence of the illness he suffered in June (12), when he spent five nights in hospital recovering.

Now Buckingham Palace officials have released a statement confirming the Duke is likely to remain in hospital for a ""few more days"" but is steadily recovering.

The statement reads: ""The Duke of Edinburgh is responding well to treatment. It is unclear when he will be discharged, but he is likely to remain in hospital for a few more days.""
