David Heslop has attempted murder sentence increased
A Cumbrian man has seen his 17-year jail sentence for the attempted murder of his former partner increased to an indefinite term by the Court of Appeal.
David Heslop, 37, from Cleator Moor, was originally sentenced at Carlisle Crown Court in November 2011.
He had stabbed Emma Wilson, 29, six times in December 2010, leaving her with life-threatening injuries.
The Attorney General, Dominic Grieve QC, argued that the original sentence was "unduly lenient".
A restraining order against Heslop had prevented him from approaching the victim or her home address.
Three judges in London quashed the sentence imposed at the Carlisle court and replaced it with an indeterminate sentence for public protection.
Lady Justice Hallett, Mr Justice McCombe and Mr Justice Singh set a minimum term of 14 years, which is the least the 37-year-old must serve before becoming eligible to apply for parole.
Lady Justice Hallett said Heslop, who had a "dreadful record for violence", subjected his "vulnerable" victim to a sustained attack which she was "fortunate to survive".
Heslop was "dangerous", and only an indeterminate sentence could "offer Miss Wilson and the public the protection they deserve", she said.
