An amazing run of success came to an end last night as a Sussex man bowed out of TV quiz show The People Versus with £65,000 in his pocket.

Ian Gretton, 53, of Southampton Street, Brighton, has been on the ITV show hosted by Kirsty Young since it started two weeks ago.

Viewers contact the show with their questions and after five successful shows, Ian was sunk by a question on the name of the architect of Canberra, saying it was William rather than Walter Burley Griffin.

He said he was stunned at first but took it in good part.

"I knew at the back of my mind I was wrong. I was disappointed but sat there for a second or two and realised I wasn't really disappointed as I had just won £65,000. How disappointed can you be having just won a prize like that?"

He competes in the weekly pub quiz at his local, the Sir Charles Napier on Southover Street, and it was his landlord Jeremy Martin who said he should put himself forward for the show.

Ian had to undergo interviews and screenings before being selected and chose English football grounds, 20th Century prime ministers, British inventors, capital cities and UK one hit wonders as his specialist subjects.

Most days in the last two weeks he travelled up to Elstree Studios in Hertfordshire to film the series.

He was going to pull out on Monday when his partner's father died but he was encouraged to go by his family and said he got lots of support from all the people on the set.

He said unlike other quiz shows like Fifteen-to-One, which he has also triumphed in, you were playing against the audience, not the other contestants, but it was still nerve-racking.
