The arrival of world leaders in Glasgow for the COP26 summit triggered a series of demos across the city.

The gathering attended by Ms Thunberg was one of dozens taking place.

She told fellow activists from "Fridays for Future" that change would not come from politicians at the summit but from individuals showing leadership.

Ms Thunberg was one of the environmental activists speaking at the "Fridays for Future" meeting of young activists at Festival Park, near the COP26 campus.

She said: "This COP26 is so far just like the previous COPs and that has led us nowhere. They have led us nowhere."

"Inside COP there are just politicians and people in power pretending to take our future seriously, pretending to take the present seriously of the people who are being affected already today by the climate crisis.

"Change is not going to come from inside there. That is not leadership - this is leadership."

The Swedish teenager led cries of "climate justice" and "no more blah, blah, blah".

"We're sick and tired of it and we're going to make the change whether they like it or not," she added.
