Animal Welfare Act 2006
The Animal Welfare Bill has now completed all of its Parliamentary stages and received Royal Assent on 8 November 2006 - it now becomes the Animal Welfare Act 2006.
A ban on the mutilations of animals (including tail docking) is included, with certain specified exemptions.
The Act does not become law until 6 April 2007 and tail docking will be subject to regulations which have yet to be drafted and consulted on, before the section on docking is enacted.
