The Duke of Edinburgh has been transferred to St Bart's Hospital in London for tests on a pre-existing heart condition. He is also said to be suffering from an unspecified infection.

He was driven by ambulance today after almost two weeks at another London hospital.

Prince Philip, who will be 100 in June, is expected to remain at Bart's for the rest of the week.
