A woman found guilty of murdering her lover on his doorstep has been jailed for life.
Sharon Akers, 33, of Letchworth, used a kitchen knife to stab Nicholas Doolan, 37, in Cheshunt, Hertfordshire, in October last year.

Judge Findlay Baker, QC told her she would have to serve a minimum of 11 years and 152 days before she could be considered for parole.
