From this vague description. He was about in Enoch Powell’s time as an MP, had a handlebar moustache and fought the government on increases in fuel prices.
Any idea? 
That sounds like him
He got prosecuted for some driving offense and fought it, claiming that one of his secretaries was driving (not Christine Hamilton husband (sic) of Neil Hamilton).
He eventually won the case and said something along the lines of ‘Justice is bought’, which was interesting as he was a solicitor (lawyer).
He lived in or around Holland Park - I often used to see his cars (with the aforementioned NAB number plates) when I was going to and from school.
That’s the one, thanks. Some of the security staff were wondering and thought to ring our office to find out
