Carney, who became leader of the Liberals and prime minister in early March, has a long track record as an international champion of climate change.As well as being a governor of the Bank of England, he was a UN Special Envoy on climate action and finance and was co-chair of the Glasgow Financial Alliance for Net Zero, one of the big outcomes of COP26.

"I think there's a missed opportunity here to set a new narrative framework around this in the election."
