The Canadian Prime Minister, Paul Martin, has been warned that voters may not support him at the next election unless he takes action to prevent the commercial growing of genetically engineered wheat in Canada.

Environmental groups urged Canadians to send a slice of bread in the post to the Prime Minister in order to voice their opposition to GE wheat, reported Agence France Presse.

“Were hoping that a huge pile of bread sitting in his office will finally force Martin to act in accordance with the will of the public on this issue,” said Anne-Marie Turmel of Friends of the Earth of Quebec. 

“The government must not introduce GE wheat in Canada,” Turmel was quoted by AFP as saying.

The Canadian government is currently deciding whether or not to approve an application by biotech firm Monsanto to allow GE wheat to be grown in Canada.
