According to wikipedia, the UK has stricter insider trading laws than the US: "The principle is that it is illegal to trade on the basis of market-sensitive information that is not generally known [in the UK]. No relationship to the issuer of the security is required; all that is required is that the guilty party traded (or caused trading) whilst having inside information."
So let's say an investigative journalist discovers that company X is involved in serious human rights abuses / environmental damage that will affect the company's share price once it becomes common knowledge. Just before he publishes his article on these abuses, if he places a spread bet or sells some shares he has in the company, could he fall foul of this law? After all, it would be "material nonpublic information" that is "not generally known."
