MHAIRI Black, Britain’s youngest MP, has dismissed suggestions she could quit politics at the next election.

Earlier this week in an interview she said she might not stand in 2020.

When asked if she will stand for re-election in 2020, the 22-year-old MP for Paisley and Renfrewshire South told the Sunday Post: “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,” she added.

However speaking at the SNP Spring Conference, she said she wanted to address the reports.

To applause from the audience, she said:” I’m going nowhere until the job is done”

In the interview she had said she still “hates Westminster”. And finds the travel between London and Paisley a pain.

And she said she was frustrated that nothing gets done.

The MP also caused a stir last week when after eagle-eyed lipreaders noticed a rather cheeky comment she made in reply to Tory Minister Caroline Nokes during a Westminster session.

Ms Black was criticising a move by the UK Government to withdraw housing benefits for 18 to 21-year-olds.

She started off by saying: “The Scottish Government cannot reverse the cut, or provide an exemption for Scotland.

“Does the minister agree that it is simply ridiculous that young people should suffer purely because this government is obsessed with imposing austerity?”

However, Ms Nokes retaliated by saying: “The Scottish Government already has a wide range of powers which would enable them to alleviate the changes being proposed here.”

It was then that Ms Black could be seen mouthing something in return.

Twitter user Katie McGarvey was the first to put forward a theory on what the Scots MP said.

She tweeted: "No much of a lip-reader but definitely mouthing, 'you talk s**te, hen'. #proud"
