The group took part in filming earlier this year in Scotland with presenter Jeremy Vine and the show’s panel of ‘boffins’ – also known as the Eggheads. The episode will be aired on Thursday 21 April at 6pm on BBC2.

The RSM team, who have already taken part in a number of local quiz nights for charity, entered for the BBC Eggheads programme after spotting an advertisement looking for contestants for the quiz show in the Radio Times.

The team consisted of Caroline Hulse, Philip Jackson, Carolyn Bailey, Matthew Hill and Ruth Pearson. The team all work together at RSM’s offices in Festival Park in Stoke-on-Trent.

Team captain Caroline Hulse said: ‘We really enjoy doing quizzes together, and we have been challenging each other to a couple of quiz questions every day in the office for a few years.

'After taking part in a few charity quizzes, we thought it would be a great step up for us to take part in one of the biggest quiz shows on TV.

'We all have our different specialist areas, and so we work well as a team and all get on really well together.

‘I don’t want to give away what happens during the episode, but I can tell you that we certainly gave those Eggheads a run for their money!’
