By what authority?

When the Thatcher and Blair governments came to power, they did so after landslide election results which  gave them a mandate for radical social change. The current UK government, headed by a Conservative party which failed to achieve a majority, has no such mandate. Yet the changes they are enacting will have profound impact on the nature of our society for generations to come. Far from tinkering at the edges, they are meddling with the very fabric of society. Such arrogance might be expected from Cameron and his cronies, but the Lib Dems are doing their reputation irreparable harm by colluding in such antics. As someone who has sometimes voted for the Lib Dems as the best of a bad bunch, I for one will never vote for them again.
