The father of murdered schoolgirl Sarah Payne has been jailed for 16 months after pleading guilty to glassing his brother.
Michael Payne, 43, admitted striking his brother Stephen on the back of his head, arm and hand after both had drunk a large amount of alcohol.
Payne, who admitted unlawful wounding, developed a drink problem after the abduction and murder of his eight-year-old daughter by Roy Whiting 11 years ago, Maidstone Crown Court, in Kent, heard.
The attack happened after he and his brother had consumed around three litres of cider each and a bottle of vodka each at his brother's home on August 24.
Sentencing Payne, Judge Jeremy Carey said he had the "deepest sympathy" for the loss of his daughter but the offence warranted a jail sentence. He will serve eight months behind bars and the remainder on licence.
Prosecutor Dominic Connolly said: "The incident occurred on August 24 when the two men were at Stephen Payne's home, and had been drinking together for some time.
"At about 10.30pm, they were sat in the front room and Stephen Payne got up to go to the toilet. As he did so, he felt a blow to the back of his head. He turned round to see his brother closely behind him and he aimed another blow at Stephen Payne's face.
"He put his arm up to block it and felt a slicing pain on his arm."
Stephen Payne fled and sought refuge at a nearby property where an ambulance was called.
He had a slice to his right hand and needed 15 stitches to the wound. He also suffered a small cut to his thumb and around a 4cm cut to the back of his head.
