A contestant on Who Wants To Be A Millionaire walked away with just £1,000 after making a huge blunder on Sunday night’s show.

Jessye Olver took to the hot seat in on the ITV game show and was left stumped by the £8,000 question.

Show host Jeremy Clarkson asked her: ‘What is the second most abundant gas in the Earth’s atmosphere?’

The four available options were either Argon, Oxygen, Carbon Dioxide or Nitrogen.

Jessye replied: ‘Pretty sure nitrogen is the first but I don’t know what the second is. I’m really upset with myself that I don’t know this.

‘But I don’t have a choice, I think I have to phone my friend. If I was sat at home, I probably would have gone with carbon dioxide, I don’t know why.’

Not fully confident, the contestant opted to use her last lifeline – Phone A Friend – to ask her pal Robert for help.

Robert was also unsure about the question, but said, like Jessye, that he would pick carbon dioxide, which Jessye chose – only to soon learn it was incorrect.

Jessye Olver took to the hot seat in on the ITV game show and was left stumped by the £8,000 question asked by host Jeremy Clarkson (pictured)

Jeremy told her: ‘I fear you have been listening too keenly to Greta Thunberg. That is the wrong answer. The correct answer, mercifully is oxygen or we’d all be in a bit of bother.’

Addressing her outcome, Jessye said: ‘I took the risk and I don’t regret it.’

It meant that she walked away from the game having won £1,000.

One viewer wrote on X: ‘Not an expert but doesn’t it have to be oxygen?’

Another penned: ‘It was a real worry regarding today’s youth when watching Who Wants To be Am Millionaire last night and the contestant was convinced CO2 was the 2nd most prevalent gas on earth after Nitrogen. She dismissed oxygen. Even Clarkson had a sly dig at her.’

A third commented: ‘About 20% oxygen breathed in, less oxygen and more carbon dioxide when breathed out.’

In last week’s episode, a contestant took home £500,000 following an ‘easy’ final question.

Andrew Fanko, 44, a translator from Market Harborough in Leicestershire, made it all the way to the million pound question – but ultimately fell short of becoming the show’s next top prize winner.

Host Jeremy Clarkson asked him: ‘Which of these is an EGOT winner, meaning they have won each of the four major entertainment awards – an Emmy, Grammy, Oscar and Tony?’

The four possible answers were A) Lin-Manuel Miranda, B) Cher, C) Andrew Lloyd Webber or D) Bette Midler.

The contestant opted to use his Ask The Audience lifeline, with Bette Midler coming out on top with 36 per cent followed by Andrew Lloyd Webber on 32 per cent.

Addressing her outcome, Jessye said: ‘I took the risk and I don’t regret it’

Lin-Manuel Miranda got 18 per cent with Cher rounding out the totals with 14 per cent.

The contestant said: ‘I’m struggling to think what Andrew Lloyd Webber won an Oscar for to be honest.’

Having set a safety net of £500,000 earlier in the show, he was unwilling to risk the life-changing sum.

With this in mind, Mr Fanko declared: ‘I will very, very gratefully take my half a million pounds please which sounds unbelievable. And that is my final answer.’

Clarkson responded: ‘It gives me great pleasure to say this, Andrew Fanko you are leaving here with your magnificently named wife, Frankie, with half a million pounds.’
