input: Article: Conservative Richard Graham is leading a campaign to increase the maximum sentence to up to 14 years.
Mr Graham said he is supporting the widow of Paul Stock, 53, from Tredworth, who died in March 2012 when he was knocked down by a disqualified scooter rider.
The man responsible for his death was jailed for two years.
Mr Stock's widow Mandy contacted Mr Graham to say the law needed to be changed to reflect the consequences of such a crime.
Mr Graham subsequently raised this issue in Parliament at Prime Minister's Questions.
Prime Minister David Cameron said the issue needed to be reviewed and the Justice Secretary, Chris Grayling, agreed the maximum sentences for disqualified drivers who caused death or serious injury were too low.
Mr Grayling has since confirmed plans to include a new clause in a Justice Bill later this year which will increase the maximum sentence.
Mr Graham said: "If in due course just one life is saved by this new clause, then Mandy's determination will have been worthwhile, and I will be very glad to have helped make it happen."

Article: Left-back Tierney was man-of-the-match as the champions moved four points clear at the top of the Premiership.
And Commons scored twice in a one-sided contest at Celtic Park.
On Tierney, Deila told BBC Scotland: "I have high hopes for him. He likes to get forward and we are going to work hard to make sure he gets even better."
The 18-year-old was upended for the penalty Commons converted to make it 3-0 just before half-time and revelled in an attacking role as United offered timid resistance.
"He's a credit to the Academy, producing players like that and more are coming. I know it," enthused Deila.
"It's great to get players like that into the team.
"He can go all the way. He has a great attitude and he has the physical, technical and tactical attributes that you need.
"You need to be mentally strong to play for Celtic and he hates getting beaten."
Leigh Griffiths opened the scoring, with Dedryk Boyata adding a header before Commons struck either side of half-time and Scott Brown ended the rout late on.
It was a good response after the disappointing midweek Europa League loss away to Molde, albeit against disorganised and dispirited opponents.
"I'm so proud of the boys, they really answered after Thursday," added Deila.
"It was a great performance and a good team spirit as well."
Commons, who issued an public apology for his reaction to being substituted in Norway, scored a penalty just before the interval and found the top corner with a wonderful shot on 53 minutes.
"He creates things all the time and he worked hard defensively," said Deila of the 32-year-old midfielder.
"He put in a good performance and I'm happy that we have him for one-and-a-half years more.
"He has always been an important player for Celtic. He has done so well in so many matches."

Question:
Article:The arrest was captured on video and Garner's words "I can't breathe" became a slogan for protesters nationwide.
Garner's death was one of a number of controversial cases in the US where unarmed black people have been killed by white police officers.
Family members had begun steps to file a lawsuit against New York, initially seeking $75m.
Police officers stopped Garner on 17 July 2014 outside a store on Staten Island for selling loose, untaxed cigarettes.
After Garner argued with police and refused to be handcuffed, officer Daniel Pantaleo put Garner in a neck hold. Garner, who had asthma, was wrestled to the ground and restrained by force. He died later at a local hospital.
"Following a judicious review of the claim and facts of this case, my office was able to reach a settlement with the estate of Eric Garner that is in the best interests of all parties,'" New York City Comptroller Scott Stringer said on Monday.
New York City did not admit to any liability. Mr Stringer has spearheaded efforts to settle civil rights case quickly, saying it saves the city money on legal fees.
The city's medical examiner's office found that Garner's death was a homicide and was caused by "the compression of his chest and prone positioning during physical restraint by police".
Critics said Mr Pantaleo performed a chokehold on Garner, which is banned by police department policy. Mr Pantaleo claimed the hold was a legal manoeuvre.
A grand jury declined last December to charge the arresting officers, setting off weeks of protests. A federal investigation into the case continues.
Garner's family plans to lead a rally pushing for federal charges against the officers on Saturday outside the Brooklyn offices of the United States attorney for the Eastern District of New York.
The Garner family and the Reverend Al Sharpton also plan to hold a news conference about the case on Tuesday.
"This is not about people getting money," Mr Sharpton told the New York Times. "This is about justice - we've got to restructure our police departments - and how we deal with policing nationwide."
