A former Angel Delight model and his friend have been jailed for life for killing a doctor during a robbery within sight of Buckingham Palace.
Nadim Gulamhuseinwala, 32, was attacked in the early hours of July 25 last year as he walked home through Green Park.
Thomas Connor and William Paton, both 20 and of Orpington, Kent, were found guilty at the Old Bailey of murder and robbery last week.
Connor, who had appeared on the instant whip dessert packet when he was 11, was given a minimum sentence of 25 years. He struck the doctor on the head with a 10kg cast iron fence pole and stamped on his face.
Paton, who searched through the doctor's pockets and stole money, was given a minimum term of 23 years' custody.
Both were given concurrent terms of 10 years' detention for robbery.
Dr Gulamhuseinwala trained as a surgeon before joining City management consultants McKinsey in 2007. He had been posted to the United States and had flown in from New York just hours before he was killed.
Judge Stephen Kramer said Connor had picked up the "fearsomely heavy" pole after spotting a man who had been drinking. The judge added: "You emerged from the shadows with your weapon, you attacked him by throwing it at his head and felled him to the ground."
The couple had spent the money which Paton took on prostitutes.
Judge Kramer said of the doctor: "He was an admirable and fine man, a charming man who had done nothing to provoke the attack on him. He was a talented man with the prospect of a promising career in front of him."
