China has stated it was the "correct decision" to launch a probe into Bo Xilai after his wife was arrested in connection with the death of British businessman Neil Heywood.
An editorial in the People's Daily, the newspaper that the Communist party uses to communicate to its cadres across the country, said Mr Heywood's death was a "serious criminal case" and that "Bo Xilai's actions have seriously violated the party's discipline, caused damage to the party and to the country, and harmed the image of the party and the country".
The investigation showed respect for the rule of law, People's Daily stated.
Speaking at a press conference during a trade mission to Indonesia, David Cameron, the Prime Minister said: "We did ask the Chinese to hold an investigation and we are pleased that they are now doing that.
"It is very important we get to the truth of what happened in this very disturbing case, this very tragic case."
A motive for killing Heywood was not spelt out, but Xinhua, the official Chinese news agency, said that Mr Bo, his wife, Gu Kailai and their son, Bo Guagua, had been on "good terms" with Heywood but that a "conflict over economic interests" had arisen.
