SNP’s Mhairi Black, 22, could stand down at the next general election as she “hates” being at Westminster and finds it “depressing”.
Asked directly if she will stand for re-election, she said: “I don’t know. I think you should only stand in politics if you think there is a need for you to be in it.”
Black became a household name after being elected the UK’s youngest MP since 1667.
She said on working at the House of Commons: “It has been nearly two years and I still hate the place. It is depressing.
“It is the personal elements – it is a pain to come up and down every week and you are working with a number of people you find quite troubling.
“Professionally, it is more just that so little gets done.
“It is so old and defunct in terms of its systems and procedures – a lot of the time, it is just a waste of time.”

The revelation that she may stand down in 2020 when the next general election is due will surprise supporters who have hailed her as a plain-speaking politician who young voters can relate to.
Last week, she made headlines when she seemingly mouthed “you talk s****, hen” while Tory minister Caroline Nokes was debating housing benefit cuts in the House of Commons.
But Ms Black says she is fed-up of being asked about her youth.
She said: “I’m sick of folk mentioning it. During the campaign, no one asked about my age, it was all in-depth political questions.
“What I always say is that trying to tailor politics to be ‘young, hip and cool’ is exactly the kind of patronising guff that puts off young folk.
“If you want to talk to young folk about politics then just talk politics. They will listen.”
She has found pals in the most unlikely of places, though, jokingly calling the Eton-educated, arch-Eurosceptic Tory Jacob Rees-Mogg “her boyfriend”.
Black continued: “I get on quite well with a lot of the Labour old guard and quite a few Tories actually.
“There is my boyfriend – Jacob Rees-Mogg. He’s my favourite.
“It’s the kind of place where, if you are reasonable with folk then they will soften a little.”
When told she is viewed by some as a future SNP leader, Ms Black laughs off the idea.
She said: “Have you seen how little personal time Nicola Sturgeon has? I wouldn’t fancy that at all.”
But asked if she would agree to be the poster girl for the Yes campaign if there’s is a second independence referendum, she said: “I would do whatever I need to do.
“It is why I got into this whole game, so aye I would. Independence is going to happen.
“I don’t know how, I don’t know when, but it is going to happen. All roads point to it.”
Outside politics, life has changed dramatically for the Paisley-born politician who has represented the seat of Paisley and Renfrewshire South since the SNP landslide in May 2015.
She has quit smoking, switching instead to e-cigarettes, and also has a long-term partner.
But while Ms Black is unsure if she wants to be an MP again, she says she is relaxed about her future.
She said: “I have a habit of falling into things.
“I fell into university, fell into this and have fallen into most jobs I’ve had.”
