A Pakistani origin Labour peer was on Wednesday jailed for 12 weeks after found guilty of being involved in a car crash that had killed one person in December 2007.
Lord Nazeer Ahmed was sentenced for dangerous driving after he admitted of texting while driving on a motorway just before being involved in the fatal crash.
Ahmed, 51, pleaded guilty to dangerous driving when he appeared at Sheffield magistrates court last year.
Martyn Gombar, 28, a Slovakian man living in Leigh, Lancashire had died in December 25, 2007 when the peer's Jaguar hit a stationary Audi car in South Yorkshire.
"After a full and thorough police investigation it's clear the dangerous driving had no causal link to the accident," Justice Wilkie on Wednesday said while clearing that the texting incident had no bearing on the fatal collision.
"It is of the greatest importance that people realise what a serious offence dangerous driving of this type is.
"I have come to the conclusion that by reason of the prolonged, deliberate, repeated and highly dangerous driving for which you have pleaded guilty, only an immediate custodial sentence can be justified," the judge was quoted as saying by
The Guardian on Wednesday.
As well as jailing him for 12 weeks, the judge imposed a one-year driving ban and ordered the peer to pay 500 pounds prosecution costs.
