Henshaw boarded a jet at Manchester Airport and set about tracking down her lover.

Paul Yabsley, prosecuting, told the court: “He immediately traced Mr Hamon to the harbour.

“He approached Mr Hamon while he was kneeling down and working on a boat. The defendant used his fists to strike Mr Hamon in the head, causing him to fall to the floor.

“As he was getting up, the defendant kicked him.

“This caused Mr Hamon to fall to the floor again, after which he was kicked in the back for a second time.”

Seconds after the attack, the battered victim told Henshaw he had “got the wrong man”. Mr Hamon needed eight stitches in his mouth and suffered bruising under his left eye and a scalp injury.

Julia White, defending, said: “My client’s wife has since said she intends to take the children with her to Alderney.

“This decision left my client feeling he has nothing to live for, as he recently lost his job as a result of taking time off work to care for the children while his wife was in Alderney.”

Henshaw pleaded guilty to unlawful and malicious wounding and was handed a three-month suspended prison sentence.

Jurat Partridge, the island equivalent of a judge, told Henshaw: “Your early guilty plea and previous good character were noted, but the Jurats cannot ignore the fact you carried out a deliberate assault.”

Mrs Henshaw was back at the family’s semi-detached home yesterday  but declined to comment, saying it was a “private matter”. The couple have an eight-year-old autistic son and a three-year-old daughter.
