GREEN activist and London mayoral candidate Sian Berry left members ecstatic following her first speech to this year’s Green Party autumn conference yesterday.

Ms Berry is a longstanding grassroots campaigner who will more likely take part in direct actions than undersign a privatisation project.

Reaching out to both the left of her party as well as the wider London left, she alluded to the new mayors of Barcelona and Madrid, elected on broad coalitions, fighting for better housing, wages and against the power of banks and big corporations.

Speaking exclusively to the Star, she said: “We are at a point where there’s actually a crisis, so there’s real, on-the-ground activism.”

Last week Ms Berry, a councillor in the north London borough of Camden, stood alongside housing activists and squatters fighting the evictions at the Sweets Way estate.

Her selection campaign was marked by a buzz she compares with the one around Jeremy Corbyn’s Labour leadership campaign.

“The Corbyn-wave needs a candidate at this election and they don’t seem to be getting one with Sadiq Khan,” she said.

“There are problems with the fact that a lot of things that are going on and that are causing the [housing] crisis are being done by Labour councils.

“Whether the whole movement comes behind me is not really relevant, it’s whether or not we can have a sort of campaign and a sort of election that’s about Londoners seizing control of London.”

Her supporters are young, Twitter-savvy, passionate and ready to donate their time and money to her campaign.

With odds better than Mr Corbyn’s original ones, much will still be written about Ms Berry until May 2016.
