The 18-year-old Swedish activist has been spotted leading COP26 climate protestors in singing "you can shove yer climate crisis up yer a***". Greta Thunberg addressed a crowd of hundreds in a Glasgow park on the first day of the climate summit. Ms Thunberg told the climate protestors global leaders were not doing enough to combat climate change before launching into the tongue-in-check singalong.

       Ms Thunberg told the crowd: ”This COP26 is just like the previous ones. It is leading us nowhere.

       “Inside COP26 politicians and people in power are pretending to take our future seriously but they are lying.

       "Change is not going to come from inside there.

       "They are not the leadership, this here is leadership.”

       The campaigner added: "No more exploitation of people and the planet.

       "No more of whatever the f*** they are doing in there at COP26."

       Footage of the climate activist leading supporters in the cheeky chanting was shared by Ms Thunberg herself on social media.

       Explaining the clip, the teenage campaigner simply put: "When in Scotland…"

       It comes as Ms Thunberg defended activists disrupting Britons going about their everyday lives to raise awareness of climate change.

       BBC presenter Andrew Marr asked the climate activist on Sunday: "There's a big controversy in Britain at the moment about tactics, something you know a lot about.

       "Blocking roads and so on. A lot of people would say those tactics just put people off."

       "Like, for instance, the school strike movement would never have become so big if there weren't frictions if some people didn't get p****d off."
