A man who murdered his estranged wife has failed in an attempt to have his conviction overturned.
Linda Razzell's body was never found
Glyn Razzell, 44, was jailed for life in November 2003 after he was found guilty of killing 41-year-old Linda.
She disappeared on her way to work at Swindon College in March 2002. Her body has never been found.
Razzell protested that DNA evidence against him was unreliable, but Judge Kenneth Zucker QC dismissed his claims, ruling his conviction "perfectly safe".
Mother-of-four Linda Razzell, from Highworth, vanished after taking her children to school and dropping her boyfriend at work.
Her husband was convicted after drops of Linda's blood were found in the boot of a car which he had access to.
Razzell had claimed he could produce fresh scientific testimony which would demolish the reliability of the DNA evidence against him, but Judge Zucker said this proof had not materialised.
