Environment campaigners protest against Vedanta in UK
The demonstrators also asked the Indian Government not to give clearance to Vedanta Mining projects in Orissa, saying that the bauxite mining company had "forced displacement, injury and illness" to Adivasis in the state.
A spokeswoman of the campaigners said that they feared the Indian government, which charged Vedanta last year with a number of environmental crimes, will now step in to reverse its own decisions.
Vedanta plc is a London-listed FTSE 100 mining corporation owned by NRI industrialist Anil Agarwal and his family.
Vedanta was reportedly denied permission to mine in the Niyamgiri Hills, home of the Dongria Kondh tribe who have been vigorously protesting against the mining.
The issue is now in the Supreme Court.
