The boyfriend of a victim of the London bombings will premiere a film he has made about her today, on the third anniversary of the attacks.

Raj Babbra, 31, from Upper Norwood made the 40-minute documentary, called 7/7: Life Without Benedetta, about his ex-girlfriend and best friend, business analyst Benedetta Ciaccia, 30, who was killed in the Aldgate blast.

He hopes it will bring home to people what it meant to lose a loved one so violently.

"I wanted to make viewers realise these aren't other people - this happened to people just like them," he said. "The fact that it didn't happen to them is more about luck than anything."

He admitted the first anniversary of the attacks was "extremely difficult" but said it had got easier with time.

The four bombs which ripped through London's transport network on July 7, 2005, killed 52 people.

Today's third anniversary will be marked with a low-key ceremony at the railway station where the four suicide bombers set out on their mission of terror.

London's Mayor Boris Johnson will join Tessa Jowell, the Government minister for the capital, and transport chiefs to lay flowers outside King's Cross station at 8.50am, the time when the first three bombs went off.

Many people will make personal pilgrimages to the sites of the four blasts - Russell Square, Aldgate and Edgware Road Tube stations, and Tavistock Square.

There will also be a private meeting for survivors and families of victims who want to share their memories and reflections.
