The sentences in the Stephen Lawrence murder trial are "only one step in a long, long journey", Stephen's father, Neville Lawrence, said.

He was speaking after the two men convicted of murdering black teenager Lawrence in a 1993 racist attack were sentenced to life imprisonment.

Gary Dobson, 36, and David Norris, 35, were given juvenile sentences, with minimum terms of 15 years two months and 14 years three months respectively.

They were under 18 at the time of the murder.

They were part of a group of white men who stabbed Lawrence to death. The others involved have not been arrested or charged because of a lack of evidence.

"I said I didn't know where I was going to go from here. One of my greatest hopes is that these people have now realised they have been found out," said Neville Lawrence.

He added that he hoped Dobson and Norris were "going to lie down in their beds and think they weren't the only ones responsible for the death of my son and give up the names of the others involved".

Stephen's mother, Doreen Lawrence, also gave a short statement outside the Old Bailey, following the sentencing of her son's murderers.

Holding back tears, she said: "It's a really difficult day, today."

She acknowledged that the "judge's hands were tied" when it came to sentencing, which is why the sentences "may seem low".

"It's the beginning, I think, of starting a new life ... Today we can start moving on and I can take control of my life once more."

She also thanked people for their support throughout the trial and urged people to donate to the Stephen Lawrence Trust, a charity promoting social justice.
