Dartford Bridge protester warned not to talk to media from prison, says partner

Marcus Decker, who is serving long sentence for non-violent action last year, reprimanded by officials

The environmental activist Marcus Decker has been warned he will lose all privileges if he talks to the media from prison, where he is serving one of the longest sentences ever passed for a non-violent protest in British history.

Four days into his jail term, Decker was visited by prison officials and told to remain silent, according to his partner. The warning came as lawyers for Decker consider an appeal against his sentence of two years and seven months for causing a public nuisance with his direct-action protest.
