The maximum penalty is two years in jail.

Boy. They really take treason seriously, don't they?

Actually, I would not believe any anonymously sourced article in the Guardian, especially for the Sunday front page. More likely, there is some law against a MP being in the pay of a foreign power, and they'll nail him on that. Hopefully sentencing can take into account that the UK was at war with said foreign power (which has been true for the past 12 years due to no fly zone defense).

The headline says "treason", the body of the article says "treachery". No place in the body of the article does the word "treason" appear.

I suspect the law they are talking about is for treachery.

Very poorly written newspaper article.
