Ian Walker's devastated fiancee Sarah Scholey led tributes to the devoted family man who was her soulmate.

Miss Scholey, 45, lived with PC Walker at Bramhope, and was to have married him last month.

She joined PC Walker's colleagues in West Yorkshire Police in welcoming Jan Tokar's eight-year jail sentence.

Miss Scholey, an executive assistant, should now have been on honeymoon with PC Walker in Australia.

She said: "Ian was the kindest most wonderful human being that you could ever wish to call your friend.

"His zest for life and enthusiasm was contagious."

Miss Scholey said PC Walker's daughter Abi, 13, parents Laurie and Barbara, and brother Mark were among those left grieving.

"The family is shattered. Ian was the love of my life. We had four wonderful years together. He was my soulmate. It is still very hard to accept that he has gone," she said.

Miss Scholey said the family acknowledged that Judge Durham Hall had treated the case with the gravity it deserved at Bradford Crown Court. "So often in road traffic cases, the balance of crime and punishment are woefully inadequate.

"The family will continue to support Brake, the road safety charity, that works tirelessly to get the severity of road traffic offences recognised and punished accordingly."

Miss Scholey said she became involved with Brake in 2006 after the son of one of her best friends died in a road accident.

After PC Walker's death, his brother Mark, 41, took part in a coast-to-coast challenge to raise money for Brake.

Miss Scholey thanked West Yorkshire Police officers for their help and support to PC Walker's family and the crash investigators for their hard work.

Detective Superintendent Chris Thompson, of the Homicide and Major Inquiry Team, said after yesterday's case: "We are satisfied with today's sentence and we hope it brings closure for Ian's family, friends and colleagues.

"Ian was a dedicated, enthusiastic and competent police officer. He was a popular and admired colleague whose quiet demeanour, willingness to help others and desire to fulfil his ambition of being a roads policing officer were highly respected."

Det Supt Thompson described PC Walker as a wonderful role model to junior colleagues.

"We are all absolutely shattered by what has occurred," he said.

He said of the sentence: "It is a very forceful message to those who drive in this manner and without insurance that it will not be tolerated."
