A Polish political leader is promising to smoke pot in his country's parliament, to protest against tough laws on soft drugs.

Janusz Palikot, leader of the left-wing Palikot's Movement, is campaigning to liberalise Poland's conservative approach to drugs policy.

His plan to roll up a joint in parliament has angered the speaker of the house, Ewa Kopacz, who has reported Palikot to prosecutors.

She has said she will not allow him to break the law in the building.

Palikot wants to introduce a draft law on 20 January, seeking the decriminalisation of the possession of small amounts of marijuana.
