The convicted child killer Beverley Allitt is to get a hearing for an appeal over the length of her sentence.
Allitt was given 13 life sentences in 1993
Allitt, dubbed the "Angel of Death", was given 13 life sentences in 1993 for killing four children and attacking nine others at Grantham Hospital.
It was later revealed she had been set a minimum tariff of 40 years before she could apply for parole.
London's High Court will hear her appeal against the length of tariff next week.
Allitt was diagnosed as suffering from Munchausen Syndrome by Proxy, where people harm others to gain attention.
