A top lawyer who has represented gangs says they will fight back against legislation that would ban patches in public.

The government expects to have the law in place by the end of this year even if it is found to breach the Bill of Rights.

It says police will be given special powers to break up gang gatherings and courts will be able to stop gang members associating with each other.

Criminal Defence Lawyer Marie Dyhrberg KC says it will not work.

Dyhrberg spoke to Charlotte Cook.
