Big on emotion and big on PR but in this clip Rory Stewart is notably short on actually answering any questions.

Filmed in Parliament Square where he was meeting students on the 24th May #SchoolStrike, he was questioned about his supposed support for drastic action on climate change given the particular insight he has from the time he was a Deputy Governer in post-invasion Iraq when BP and other corporations carved up the spoils of war with massive 20-year fossil-fuel extraction contracts.

He was also asked about City of London corporate influence on the Conservative Party – the Chief Executive Officer and Treasurer of the party is currently Mick Davis, who also made large donations during his time as head of mining giant Xstrata.
