Sinha later revealed in a blog post that he had been overwhelmed by the victory and spent two hours weeping privately as he reflected on his achievement.
"The weeping. It had nothing to do with Parkinson's. Although I am realistic enough to know that this was probably my one big shot at a major title," he wrote.
"It had everything to do with the fact that I have worked my bloody arse off for the last ten years, travelling around the country and indeed Europe just trying to compete, enjoy and improve.
"For the next 12 months, I'm the British Quiz Champion. Parkinson's will not be able to take that away from me."
Sinha has previously made clear his intentions to "keep Chasing, keep writing and performing comedy [and] keep quizzing." He joked that an appearance on Dancing on Ice was probably "out of the question".
Sinha and Labbett appear on The Chase with the likes of Shaun Wallace, Anne 'The Governess' Hegerty and Jenny Ryan.
