A court in the northern Indian state of Bihar has sentenced a controversial politician to life in jail for kidnapping one of his rivals.
Mohammad Shahabuddin is being tried in dozens of cases
Mohammad Shahabuddin, an MP from the Rashtriya Janata Dal party, was found guilty of the 1999 abduction of communist politician Chhote Lal Gupta.
Mr Gupta has never been traced and police have concluded he was killed.
Shahabuddin faces charges in more than 30 other cases. His lawyers say they plan to appeal against his sentence.
Nearly one in every six legislators in India's national parliament and state assemblies faces criminal charges.
The Rashtriya Janata Dal is part of the Congress party-led federal coalition which governs India.
Announcing sentence in the town of Siwan, judge Gyaneshwar Prasad Srivastava said he found Shahabuddin guilty of "kidnapping with intent to murder".
The MP was also ordered to pay a fine of 10,000 rupees ($230).
Investigators say Shahabuddin kidnapped Mr Gupta, who went missing on 7 February 1999, with the help of two others.
They remain unidentified and the MP was the lone accused named in the police report.
In March, the MP was sentenced to a two-year jail term in another case relating to a 1988 attack on a Communist Party of India (Marxist-Leninist) office near Siwan, about 100km (62 miles) north-west of the state capital, Patna.
He is being tried in dozens of other cases, including murder, kidnapping, attempted murder, possession of illegal firearms, violating the wildlife act and stealing vehicles and electricity.
Opposition parties in the state have demanded that Shahabuddin's membership of parliament be annulled.
