Hi!
For those who are interested...
Not had time to find the relevent sections, but on the Uk goverment website [url=http://www.hmso.gov.uk]
all the laws are published. As far as I can work out the relevent Acts of parliment are the Criminal Justice Act 1988, the Offensive Weapons act 1996 and the Knives Act 1997.
Just search the site for those names or Google them and you should come up with the laws.
