HILLARY Clinton has issued a warning over COP26 success one week before the Scottish climate summit.

Scotland will host the UN climate change talks, which start on October 31 and run until November 12.

As many as 30,000 people are expected to attend the event in Glasgow, with delegations coming in from all over the world. Argentinian president Alberto Fernandez, Emmanuel Macron of France and Canada's Justin Trudeau are amongst those expected. There was a question mark over India's Narendra Modi, but his attendance was confirned two days ago.

However, Russian president Vladimir Putin and Chinese president Xi Jingping are not set to join America's Joe Biden and others.

In an interview with The Andrew Marr Show, Clinton today said she was "very disappointed" that "major emitters" including China and Russia will not be present.

The former US secretary of state said: "I think we will have an agreement, I think we will have a lot of countries showing up, saying 'we are getting serious, we have seen the results in our country, we have seen floods and droughts and terrible intense storms, wildfires everywhere'.

"I think we will have an agreement, but if these three big emitters — most particularly China — don't come to the table, whether their leaders are there or not, and say 'we have got to be part of the solution', then it's not a failure for Glasgow, it's a failure for them and they are going to reap the consequences but so will we all."
