The US and the UK vary in the way the law is interpreted and applied with regard to insider trading. In the UK, the relevant laws are the Criminal Justice Act 1993, Part V, Schedule 1; the Financial Services and Markets Act 2000, which defines an offence of "Market Abuse"; and the European Union Regulation No 596/2014. The principle is that it is illegal to trade on the basis of market-sensitive information that is not generally known. This is a much broader scope that under U.S. law. The key differences from U.S. law are that no relationship to either the issuer of the security or the tipster is required; all that is required is that the guilty party traded (or caused trading) whilst having inside information, and there is no "scienter" requirement under UK law.
