CCTV of the clash showed the property lawyer, of Maida Vale, north London, being stopped from passing by Mr Ghadami during an exchange inside the court in April last year.

He then swung his case between Saunders' legs, prompting Saunders to lunge forwards and headbutt him.

The pair had both been involved on opposing sides in an ongoing land dispute being heard at the court.

Sentencing, Recorder Steven Gasztowicz QC said Saunders had completely lost his self-control when he "quite deliberately headbutted him".

He said it was "clear from the CCTV footage that you could have left his presence without doing anything like that".

"The offence was committed in a High Court building where any litigant" should "feel safe, however annoying they may be and whatever is going on".
