A Hitchin man has been charged, alongside climate activist Greta Thunberg and 24 others, with public order offences after a protest outside a London oil summit.

31-year-old Joshua Unwin was charged with failing to comply with a condition imposed under Section 14 of the Public Order Act, and has been bailed before appearing at Westminster Magistrates' Court on November 15.

Famous climate activist Thunberg was among those charged after hundreds of protestors gathered outside the InterContinental on Park Lane, the venue for the Energy Intelligence Forum, which brings together fossil fuel executives and government ministers.

"We have charged 26 people after a protest outside a hotel in central London," said the Met Police.

"Officers responded to the protest on the morning of Tuesday, 17 October and imposed conditions to prevent disruption to the public.

"The protestors were asked to move from the road onto the pavement, which would enable them to continue with their demonstration without breaching the conditions."

Previously known as the Oil and Money Conference, protestors dubbed the event the "Oily Money Conference".

Before joining the protest, Thunberg told reporters: "Behind these closed doors at the oil and money conference, spineless politicians are making deals and compromises with lobbyists from destructive industries, the fossil fuel industry.

"People all over the world are suffering and dying from the consequences of the climate crisis caused by these industries who we allow to meet with our politicians and have privileged access to.

"The elites of the oil and money conference, they have no intention of transition. Their plan is to continue this destructive search for profits.

"That is why we have to take direct action to stop this and to kick oil money out of politics. We have no other option but to put our bodies outside this conference and to physically disrupt it."
