The son of a former police and crime commissioner (PCC) who killed a woman with his tractor has been jailed for 42 months following a retrial.

Henry Bett, 28, son of Norfolk's former PCC Stephen Bett, was found guilty of causing the death of 43-year-old Rebecca Brown by dangerous driving at a retrial Cambridge Crown Court this month.

He had been jailed for three-and-a-half years in 2015 but the conviction was quashed at London's Court of Appeal in September 2016 and a retrial was ordered.

The jury at this month's retrial found Bett guilty by a majority verdict of 10 to two and he was sentenced at Peterborough Crown Court on Friday.

Judge Sean Enright said he had wanted to jail Bett for 44 months, but the law prevented him from imposing a sentence greater than the original one.

He jailed Bett for 42 months and banned him from driving for five years.

The family of mother-of-four Mrs Brown sat in court as the sentence was read out.

Judge Enright told Bett: 'This is a very painful episode in their lives and for that family, life will never be the same again.

'She was a much-loved mother, wife and daughter.'

Bett, of Hall Lane, Thornham, Norfolk, killed mother-of-four Mrs Brown when he drove his tractor head-on into her Fiat people carrier in Castle Acre, Norfolk, in December 2013.

Her teenage son was in the car with her at the time.

Adrian Foster, Chief Crown Prosecutor for Thames and Chiltern Crown Prosecution Service (CPS), said: 'This was a very sad case, the consequences of which have had a terrible impact on many lives.

'The victim, 43-year-old Rebecca Brown, was a wife and mother, and her family and friends have been devastated by her death.'

He said Bett was travelling in the middle of the road and failed to take sufficient steps to avoid a collision.

Det Insp Scott Egerton, from the Essex Police Serious Collision Investigation Unit, which investigated the crash, said: 'This case highlights the tragic consequences of failing to act responsibly when behind the wheel of a vehicle.

'Rebecca Brown lost her life in circumstances that were wholly avoidable and Henry Bett will have to pay the price for his dangerous driving. All road users, especially those driving larger vehicles, need to consider other people; particularly those who are more vulnerable than themselves.

'Holding a driving licence brings with it a high degree of responsibility that should always be at the forefront of a driver's mind. Not doing so, as in this case, can have devastating results for all those concerned.'
