The husband of British soul singer Amy Winehouse was ordered to serve about four and a half more months in prison on Monday after he pleaded guilty to attacking a pub landlord in 2006 and then trying to cover it up.

Blake Fielder-Civil, 26, sat with his three co-defendants before judge David Radford  in east London as the sentences were read out.

“I read that you, Blake Fielder-Civil, were affected by drink and cocaine and that in that drunken and drugged state took part in this attack out of a mistaken sense of loyalty to your friend Michael Brown,” Radford said.

He added that Fielder-Civil, who married Winehouse in Miami in 2007, “behaved in a gratuitous, cowardly and disgraceful way”, and sentenced the former video assistant to 27 months in prison, of which he will only have to serve half.
