A man who strangled his wife as their baby son slept in the same room has been given an indeterminate jail sentence.
Ronald Tyler, 47, was told he must serve a minimum of eight years for the manslaughter of Julie McKinley, 40, at their home in Finsbury, north London.
He attacked her following a row after she returned from a party on 31 December 2009.
Tyler, who was cleared of murder, was sentenced at the Old Bailey.
After Ms McKinley's death, he dialled 999 to say where the body was and told police to be careful as the children were asleep.
Her body was found in a bed in the same room as her 22-month-old son.
Her eight-year-old daughter, who was in another room with two younger sisters, shouted out "she's in there" when officers arrived.
Jurors heard Tyler was "obsessively jealous" and he claimed he strangled her after she told him their baby was not his.
The court heard he had convictions for 44 separate offences since 1977, 14 of which were for violence or threatening and abusive conduct - four of them involving his wife.
There were also 20 other reports made to police by Ms McKinley between 1996 and 2009 of alleged violent or abusive behaviour which she did not pursue.
In addition, Tyler admitted to a psychiatrist that he had "slapped" three other women during three previous "turbulent" relationships.
In November 2008 he was convicted of common assault against his wife and given a suspended sentence.
After breaching the suspended sentence he was given a 52-week jail term in July last year but was released two months before the fatal attack.
Judge Jeffrey Pegden told him: "You held the power in the relationship and the deceased frequently relented and took you back after your violent and threatening behaviour."
He gave Tyler an indeterminate sentence for public protection, telling him he posed a significant risk of "serious harm" to members of the public, in particular "any female you are in a relationship with".
Tyler was cleared of murder but found guilty of manslaughter on the grounds of provocation by a 10-two majority.
