Prime Minister Sir Keir Starmer has said the UK will show “responsible global leadership”.

In his speech to the UN General Assembly in New York, Sir Keir announced a new British International Investment initiative.

The new scheme will see the Government working with the City of London to use billions of pounds from pension and insurance funds “to invest in boosting development and fighting climate change”.

Sir Keir also called for a new international levy on global shipping to “put a price on the true cost of emissions” with the money raised going to tackle climate change.

The Prime Minister also demanded changes to the UN Security Council “to become a more representative body” which was “willing to act – not paralysed by politics”.
