The first speech made by the UK's youngest MP has already racked up more than 10 million views online after less than a week.

Scottish National Party (SNP) politician Mhairi Black has been widely praised for her maiden contribution in the House of Commons, which was made during a Budget debate last Tuesday.

In her speech, the 20-year-old attacked to Conservative Government and Labour's limp opposition.

''I have heard multiple speeches from Labour benches standing to talk about the worrying rise of nationalism in Scotland, when in actual fact all these speeches have served to do is to demonstrate how deep the lack of understanding about Scotland is within the Labour Party," she said.

''I, like so many SNP members, come from a traditional socialist Labour family, and I have never been quiet in my assertion that I feel it is the Labour Party that left me, not the other way about.

"The SNP did not triumph on a wave of nationalism; in fact nationalism has nothing to do with what’s happened in Scotland. We triumphed on a wave of hope, hope that there was something different, something better to the Thatcherite neo-liberal policies that are produced from this chamber. Hope that representatives genuinely could give a voice to those who don’t have one."

'The views include 5.5 million views on Channel Four News' Facebook page, three million views on Buzzfeed UK and more than 650,000 views on the SNP's Facebook page.

Ms Black, who represents Paisley and Renfrewshire South, is the youngest MP since the 17th Century.

SNP Westminster leader Angus Robertson said Ms Black's maiden speech was principled and passionate.

"The House of Commons listened in silence to its youngest member remind us all why we are sitting in our place and those we were elected to speak for - it is of no surprise that this message had resonance far beyond the walls of Westminster. That millions of people across the UK and abroad watched her speech is staggering.

"Mhairi has an enormous contribution to make to parliament - she is one strong voice of 56 elected to stand up for Scotland and for progressive change across the UK."
