Wheel clamper Bellfield, 39, was convicted at the Old Bailey of killing students Marsha McDonnell and Amelie Delagrange.

Bellfield was also found guilty of attacking schoolgirl Kate Sheedy.

The jury of seven women and five men, which retired last week, was unable to reach verdicts on two other assault charges.

The prosecution alleged that Bellfield, from west London, trawled buses and bus stops for women and attacked them when they rejected him.

Bellfield told the three-and-a-half-month trial that he was the victim of mistaken identity. But he was convicted of murdering French student Miss Delagrange, 22, in August 2004, and Miss McDonnell, 19, from south west London, in February 2003. Both were hit on the head with a heavy object.

Bellfield was also charged with the kidnap and false imprisonment of Anna-Maria Rennie, 17, and the attempted murders of Miss Sheedy, 18, and hairdresser Irma Dragoshi, 33. The attacks all took place between 2001 and 2004 near bus stops in the Twickenham area of west London.

Miss Sheedy was left for dead after Bellfield ran her down in his car as he trawled the streets for victims late at night.

The jury convicted Bellfield unanimously of the murder of Miss Delagrange. Majority 10-2 verdicts were reached for Miss McDonnell's murder and the attack on Miss Sheedy.

The jury was unable to reach verdicts in connection with two other attacks, on Anna-Maria Rennie, 17, in Whitton, south west London, in October 2001, and Irma Dragoshi, 33. in December 2003. Both women were at bus stops when they were attacked.
