COP26: World leaders address delegates

World leaders and activists have been addressing the delegates at the COP26 climate summit. We'll bring highlights of the main speeches and talking points at COP26. We also explain what is happening in global climate negotiations like COP26 and what’s expected from this gathering.

Among those who won’t attend the summit are the Chinese and Russian presidents. We’ll speak to our BBC Chinese and BBC Russian colleagues about why the two leaders are not there, and what their climate plans are.

Many eyes are also on the US, the world’s second-biggest emitter of carbon. We’ll speak to two journalists about two Senate Democrats from their states -West Virginia and Arizona - who are refusing to back President Biden’s climate package.

We’ll discuss today's Covid stories with our regular coronavirus expert - Dr Eleanor Murray - assistant professor of epidemiology at Boston University School of Public Health.
