Women centre stage as the COP clock ticks

Speaker of the US House of Representatives, Nancy Pelosi, arrives in Glasgow and Ashna Hurynag wastes no time asking her how negotiations are going.

But she's not the only powerful woman on this episode. We also hear from Chair of the Elders Mary Robinson, indigenous leader Helena from Ecuador and International Trade Secretary Anne-Marie Trevelyan.

Plus as negotiation time is running out, Ashna speaks to Science and Technology editor Tom Clarke, who is sat with a cold tea and soggy teacake.
