Confused.com have suggested a novel theory for John Sergeant's motives behind quitting the BBC's hit reality show Strictly Come Dancing.

John Sergeant became the unlikely hero of thousands with his incompetent performances on the show, prompting judges to famously describe him as a 'dancing pig.'

However, despite incurring the judges wrath week on week, the public took John Sergeant's endearing inadequacy to heart and kept voting to save him, resulting in him lasting until last Thursday, when he sensationally quit the show.

On his reasons for quitting, Sergeant released this statement: "I am sorry to say I have decided to leave 'Strictly Come Dancing'. It was always my intention to have fun on the show and I was hoping to stay in as long as possible."

However, he added that: "The trouble is that there is now a real danger that I might win the competition. Even for me that would be a joke too far."

Outraged fans posted messages on the show's website such as "Absolute disgrace and a huge blow for democracy" and "This is so wrong I just don't have the words", with one disgruntled viewer even describing John Sergeant as a 'Martyr'.

In the wake of his exit, various news sources have come up ulterior motives behind the move, suggesting that he has a holiday booked, is performing on a cruise ship, or was simply bullied into submission by 'elitist' judges.

Confused.com have jumped on the bandwagon with the most inventive reason yet, suggesting that he may have been worried about the cost of his car insurance rising by as much as £124.75 had he made a change in career and become a professional dancer, rather than a journalist.

The website found that job title can be an important factor when taking out car insurance, with seemingly similar jobs resulting in vastly different quotes. For example, the difference between an entertainer and a singer can be as much as £223.

Will Thomas, head of motor insurance, says: "It is certainly true that using different ways to describe a person's occupation could dramatically reduce their premiums, although it is important not to confuse being savvy with being dishonest.

"The increase is mainly due to risk association, a dancer could be performing behind Robbie Williams or Kylie Minogue on stage, socialising with them, then driving them home at night.

"If the car crashes while they're in the car, the driver could be liable for their loss of earnings, which in the case of Robbie or Kylie is going to be considerably more than the average person. So it really is who you know, not what you know!"

Working in an office rather than on the move can make a large difference in the cost of premiums, so it is important to carefully consider whether an alternative or more accurate description of your occupation could lower your premiums.

For example, a journalist could be employed in a range of high risk activities, driving to the scenes of news stories, or could be exclusively office based, which would make a dramatic difference to the cost of their car insurance premiums.
