The Prime Minister said his focus is delivering “a better future” for Britain as he set off for the G20 summit in Rio de Janeiro, Brazil.

In a post on X, formerly Twitter, Sir Keir Starmer said: “My focus at the G20 summit this week is delivering for the British people.

“More jobs, more prosperity, more security. A better future for our country.”

The Prime Minister will be discussing how to strengthen the UK’s economy and get investment into country as well as security issues, he said in an Instagram video posted from the flight to Brazil.

The G20, or Group of Twenty, meets to discuss global economic and political issues with discussions likely to include Ukraine, conflict in the Middle East and environmental issues.

He plans to talk to his counterparts about illegal migration and energy independence.

“Let’s be clear – these global problems are connected. A world of deeper conflicts and catastrophic climate change would lead to even greater waves of migration and a fatal blow economic growth.

“So we must be strong to protect Britain from that future. We should look out to the world now with confidence – buoyed by strong alliances, ready to stand up for our principles,” Sir Keir wrote in an article for The Sunday Express.

France, Germany and Italy as well as China, India and Mexico are among the G20 nations.

It will be one of the last outings on the world stage for US President Joe Biden before Donald Trump enters the White House in January.
