Nicholas Clements, of Austin Edwards Drive, pleaded guilty at Warwick Crown Court last week to wounding his victim.

Prosecutor Glyn Samuel said the 37-year-old had been in a relationship the woman but the pair split up last May.

On December 22 Clements went to a pub with his ex-girlfriend's lodger before going back to her home.

Once there, the defendant became abusive and accused her of having an affair with the man.

He punched the victim several times and hit her on the head with a wine glass he was holding, causing a 4cm wound.

The defendant also kneed her in the face during the attack, fracturing her jaw.

The woman managed to get him out of the house but he got back in and was restrained and thrown out by the lodger.

The police were called and Clements was arrested as he was walking away
When he was questioned about the incident the defendant accepted he had punched the woman while he had the glass in his hand but said he could not remember doing it.

He also broke her glasses and caused £300 damage to the door.

Nick Devine said there is no dispute it passes the custody threshold. It is just a question of how long the sentence is.

He said that the attack carried out by Clements, who was of previous good character, had not been premeditated and that Clements expressed remorse and genuine regret' for what he did.

Jailing Clements, Judge Marten Coates said: "It is very sad when someone who has reached the age of 37 appears before the court for the first time.But you acknowledge you caused that injury to her head.

"This court often deals with cases of domestic violence and injuries caused in drink. I have to pass a custodial sentence, but I give you full credit for your previous good character and your plea of guilty at the earliest opportunity."
