Greenpeace supporters will hold protests at over 70 Shell petrol stations across the country in support of the 'Arctic 30' today.
It comes as Russian officials have signaled they will ask that the Greenpeace group be detained an extra 3 months - meaning they could be behind bars over Christmas.
Activists will be asking bystanders to sign a petition asking Shell to pull out of their joint oil drilling venture with Gazprom.
Protests will take place across Shell's petrol stations in London, including: Bayswater, Holloway Road, Old Street, Southwark, Whitechapel, Grosvenor Road, Lewisham, Richmond Road and Staines Road.
