Birmingham love triangle killer Karla Biddle, jailed for seven years for stabbing her rival to death at their two-timing boyfriend’s home, is being released from prison after serving less than three years.

The former human resources manager slashed Emma Bradshaw 56 times with a kitchen knife, fatally wounding her in the lungs and abdomen, in May 2008.

Thirty-year-old veterinary nurse Miss Bradshaw was in a relationship with Biddle’s ex-fiancé Ashley Watson at the time.

She was found bleeding to death in the middle of the road outside Mr Watson’s Solihull home after she ran out to try to get help from neighbours.

Biddle, who lived in Aldbury Road, Yardley Wood, was jailed for seven years for Miss Bradshaw’s manslaughter in April 2009.

A jury found her not guilty of murder but guilty of manslaughter on the grounds of provocation.

Now Miss Bradshaw’s family have been told Biddle is being let out of jail in the next week – just two years and eight months after she was sentenced.

The Ministry of Justice has written to the Bradshaw family to inform them of their decision to let Biddle out of jail in mid-November.

The letter says that Biddle, aged 34, who will remain on licence until May 2015, plans to live in south Birmingham.

It states: “I have been informed by Karla Biddle’s probation officer that she will be released from prison mid-November this year. Her plans are to reside in south Birmingham on release.”

Michael Bradshaw, a retired teacher, of Sutton Coldfield, was too upset to speak about the imminent release of his daughter’s killer.

But a friend of the family said Emma’s relatives were struggling to cope with her death three years on.

He said: “They will never get over losing their wonderful daughter in such a brutal way. Each day is a struggle.

“First her killer gets to go home for Christmas and now she is being released early, less than three years into her sentence. They don’t feel justice has been done.”

Biddle was let out of prison at Christmas last year on a temporary licence.

During the trial at Warwick Crown Court, the jury was told Biddle met Mr Watson at school and that they had been a couple since 1993.

They bought a house together in 2002 and were engaged the following year. The wedding plans were put on hold as cracks appeared in their relationship. Mr Watson moved out in 2007 after meeting Miss Bradshaw. But the jury was told he continued to sleep with Biddle.

He said he loved both women and could not break up with either of them.

After the attack, Biddle drove to work at Royal Sun Alliance in Birmingham as if “nothing had happened”, according to Judge Richard Griffith-Jones.

She sent Mr Watson a text message in an attempt at an alibi and spent the afternoon sunbathing.

At the end of the trial the judge described the case as an “absolute tragedy” in which there were “only losers”.

A spokeswoman for the Ministry of Justice said: “Sentencing is matter for the courts.

“Under the Criminal Justice Act 2003, offenders given a determinate sentence, longer than 12 months, serve half their sentence in custody and half in the community supervised by Probation. Time served on remand counts towards the custodial part of the sentence.

“All offenders subject to probation supervision on release from prison have to adhere to a set of strict conditions.

“They are subject to recall to custody if they breach their conditions or their behaviour indicates that it is no longer safe for them or for the public if they remain in the community. “
