David Cameron's eldest son Ivan has died in hospital, the Conservative leader and North Kensington resident announced this morning.

The six-year-old was born with cerebral palsy and epilepsy and needed round-the-clock care at the family's home, off Highlever Road,  North Kensington.

Ivan, who Mr Cameron described as "wonderful", was a regular in-patient at St Mary's hospital in Paddington. He also used to be treated at the now-closed Cheyne Day Centre in Chelsea and Westminster Hospital, Fulham Road, Chelsea.

Mr Cameron had been an MP for less than a year when Ivan was born in April 2002. He and wife Samantha have two younger children, Nancy and Arthur.
