Prosecutor calls for 'severe' sentences for fallen Chinese politician Bo; trial phase wraps up

JINAN, China - The trial of disgraced Chinese politician Bo Xilai has closed, with prosecutors saying he deserves a severe sentence because of his lack of remorse over alleged corruption netting $4.3 million and abuse of power in interfering in a murder investigation.

Prosecutors said Monday that adequate evidence of Bo's guilt was presented during the four-day trial, which is aimed at cementing Bo's political downfall and wrapping up the scandal set off by his wife's murder of a British businessman.

Bo has denied the charges against him and assailed the prosecution's key witnesses — his former right-hand man and his wife.

Sentencing is expected next month.

China's recently installed leadership is hoping to move on from the scandal as it tries to cement its authority and focus on economic and social challenges.
