The vote took place during its founding conference in Dundee on Sunday, with 63% of the party’s members backing the move.
The wording of the agreed motion stated: “Your Party Scotland believes that an independent Scotland is the best route to improve the lives of people in Scotland and achieve socialism.”
It comes not long after a speech from one of the party’s co-founders, former Labour leader Jeremy Corbyn, who said that if the people of Scotland want to hold an independence referendum then “that is their choice”.

Corbyn, who currently sits in Westminster as an independent MP, said: “As far as I’m concerned, I’ve always had the position that if the people in Scotland and the Scottish organisations want a referendum to decide the future of Scotland, that is their choice.
“It should not be determined by the UK Government in Westminster, and I think we have to make that very, very clear indeed.”
It also comes after members decided that Your Party will also be standing candidates in this year’s Scottish Parliament elections.
Immediately after that was announced, Zarah Sultana – who is the party’s only Westminster MP – gave a speech in which she took aim at the SNP and Scottish Greens.
The Coventry South MP said: “Scottish people deserve better than a politics that wears the veneer of progressivism while still pushing through cuts that decimate our communities, and that’s what you get with the SNP and the Greens.”
She added: “We can do better than that.”
Speaking afterwards, Ellie Gomersall, a member of Your Party Scotland and one of the conference’s organisers, said: “From agreeing our position in support of independence, to committing to stand candidates in select regions in the upcoming Holyrood elections, this weekend members across Scotland proved our commitment to becoming a serious political force that will put in the work to transform Scotland and improve people’s lives.
“With the far right on the rise and governments in both Holyrood and Westminster passing on cuts to local communities, the need for a real anti-establishment party to challenge the status quo couldn’t be more needed – and that’s exactly what Your Party Scotland is here to do. This weekend is just the beginning.”
Owen Maitland, another member and conference organiser, added: “The decision by Your Party Scotland to support independence was one of the most consequential that members made this weekend.
“It’s clearly the only logical choice for a socialist party – folk often like to suggest that independence is a side issue or a distraction, but that couldn’t be further from the truth. It’s about everything from our hospitals, our schools and our political system to who controls our economy. If that isn’t a class issue, I don’t know what is.
“Members have fundamentally recognised that a socialist programme and Scottish independence go hand in hand, and have voted overwhelmingly to support independence as a result. This has also taken away the SNP’s only silver bullet – we can now focus clearly on their record in government.”
