Cop26: Boris Johnson talks the talk but can he really deliver a climate deal?

This week's talks in Glasgow will be a test of commitment. But there has been little hard diplomacy from Britain, the host nation, to ease the path to an agreement

Anyone who listened to Rishi Sunak's budget speech last Wednesday could be forgiven for concluding that there is nothing particularly urgent for people to worry about - economically or existentially - on the climate front.

The chancellor was 35 minutes into his third budget address to MPs before he even alluded to matters environmental. And when a reference finally came it was a fairly brief one - to the government's ambitious net zero strategy" - of which he is said to be no great fan. Throughout the entire budget, Sunak did not use the phrase climate change" once.
