What does british wrongs mean?

There's no such term- 'rights' and 'wrongs' are casually generic terms used by the media to describe certain aspects of political behaviour or attitude on the part of the Government and / or Opposition in relation to certain policies or implementations of law, but it's not an official term used by anyone other than when somebody (or someTHING such as a Company) breaks the law, when they are 'in the wrong'.
