Andrea Dykes, 27, who was four months pregnant, and the best man at her wedding, John Light, 32, were killed along with a friend, Nick Moore, 31.

Mrs Dykes' husband, Julian, 26, a computer programmer at a college, is still unconscious after being seriously injured.

He has nails lodged in his lungs, and his family is maintaining a vigil at his bedside in University College Hospital in London.

John Light died in the bomb

Mr and Mrs Dykes and John Light, all from Colchester, had travelled to London to see the Abba musical Mamma Mia. They had met up with Mr Moore, an office worker who lived in London.

Mrs Dykes, who worked at a bingo hall had been married in August 1997.

The minister who married the couple said there was a palpable sense of sadness'' when he broke the news in church.

The Rev David Thomas, of St Mary the Virgin Church, said: "The news has come as a major shock. People feel sad and upset because it has brought the reality of the bombing close to them at home."

He said Mrs Dykes had only recently discovered she was pregnant.

The couple had just chosen Mr Light, best man at their wedding, as a godparent.

Mr Light's family said in a statement on Monday:

"We are devastated to lose John to such a senseless act of violence.

"John was a popular, loving, well-respected man who enjoyed nothing more than being with all his friends."

Nick Moore...his parents visited the scene on Monday

Police have charged a 22-year-old engineer, David Copeland, of Cove, Hampshire, with murder following the three attacks.

A vigil has been held in Soho Square to commemorate the dead and to show support for the injured.

Four people are still fighting for their lives and 15 victims of the attack remain in hospital.

Justin Cobb, consultant orthopaedic surgeon at University College Hospital said: "There were the most appalling injuries.''

War scenes

Life-saving surgery was carried out on the victims over the weekend and Mr Cobb added: ''We were taking out huge pieces of glass, six-inch nails and fragments of metal."

Professor Gus McGrouther, professor of plastic surgery, said the injuries were worse than those seen in IRA attacks and among war victims.
