Lower House Getting Higher

Police made a surprising discovery outside the seat of government on Thursday -- marijuana plants have sprouted at the House of Commons.

Two months after environmental activists dug up Parliament Square in a guerrilla gardening protest, the small park near the Commons has sprouted with carrots, onions, marigolds and that weedy plant, marijuana.

During the May Day protest, 600 people descended upon Parliament Square, and the protesters apparently cultivated a little cannabis along with the vegetables.

Royal Parks Police said the plants had been identified by horticulturists on Thursday as cannabis and that police would clear them away with other plants and flowers.
