Activists with Just Stop Oil have graffitied a building housing right-wing think tanks and blocked the road in Westminster.
Officers said one person had been arrested on suspicion of criminal damage after protesters spray painted 55 Tufton Street in Westminster, an address linked to several influential right-wing organisations.
Six protesters disrupted traffic by sitting in the road with banners, with some supporters fixing themself onto the tarmac, while others locking themselves together.
Activists said they targeted the building because it was the “headquarters of fossil fuel lobbyists that backed Liz Truss”.
The building houses organisations including the TaxPayers’ Alliance and the Global Warming Policy Foundation, an organisation which questions the cost of policies attempting to address climate change.
