COP26: New draft deal to be announced Saturday morning

The UN climate summit has officially run into overtime, with policymakers missing a 1800 GMT deadline Friday to ratify a binding deal. Alok Sharma, the British chair for COP26, says an agreement will be announced this morning.

Also in the programme: Today marks 20 years since the Taliban were first driven out of power in Afghanistan -- only to return with an even more secure footing in recent months. Our World Affairs editor, John Simpson, takes us on a journey through the years in Kabul. And our correspondent Jenny Hill gives us an update on the migrant crisis in Belarus and Poland, from the border on the Polish side.

Joining Celia Hatton to discuss these and other issues are Rachel Kyte, an advisor to the UK government for COP26 and Gavin Jennings, presenter of Ireland's most listened-to radio programme, Morning Ireland.
