Greens become third-largest political party in the UK

Membership of the Green Party has overtaken the Conservatives, making them the third largest party in the country.

The party now has more than 126,000 members, an 80% increase since Zack Polanski was elected as leader last month. 

After his appearance on BBC One’s Laura Kuenssberg show, Polanski said the Green Party saw 1,000 new members join in just over two hours. 

The party’s leader insists that “British politics is changing” and previous “support for old-style parties” is “shrinking”.

The Green Party is gradually climbing the polls in voting intention, but Reform UK close to the top with over 260,000 members.

The last official figures published in August 2025 shows that Farage’s party need only 70,000 more members to match with Labour. 

While countering Reform, the Green Party reportedly now have more than double the members of the Liberal Democrats. 

Polanski declares that more people in the country are “choosing a new kind of politics” where they’re offered “a bold, hopeful vision of prosperity, equality and unity”. 

A rise in support for the Greens suggests many are moving away from a “broken” two party system, according to Polanski.

Their increase in numbers “reflects growing public frustration with the political status quo”.
