"The prime minister has reversed an earlier decision not to go to the COP27 climate summit in Egypt.
No 10 had said Rishi Sunak was too busy preparing for the 17 November budget to attend the event which opens on Sunday.
But this had been widely criticised by climate campaigners, opposition parties and climate adviser Alok Sharma.
Mr Sunak tweeted that there would be "no long-term prosperity without action on climate change" or energy security without investing in renewables.
"That is why I will attend @COP27 next week: to deliver on Glasgow's legacy of building a secure and sustainable future.""
