Greta Thunberg tells the BBC that a "change is possible" during the climate summit, if the pressure on politicians continues.

When asked if she has been asked to speak at the meeting, she says:

- I do not know.

It is very unclear.

Not officially anyway.

This weekend, the UN climate summit COP26 begins in Glasgow, Scotland.

Ahead of the opening of the meeting, a number of protests took place last week, including in London's financial districts outside several banks.

The protesters demanded that the financial world stop investing in projects with fossil fuels.

Greta Thunberg was one of those who participated, but has now arrived in Glasgow.

The British tabloid Daily Mail writes that the Swedish climate activist received a "rock star reception".

Greta Thunberg wrote shortly afterwards herself on Twitter that she was happy to have finally arrived in Glasgow and thanked for the warm welcome.
