Boris Johnson has pledged to reform Britain’s archaic treason laws in order to better deal with transnational terrorist groups.

The Prime Minister will today announce a major integrated defence, security and foreign policy review which will commence after Brexit.

As part of the review, Britain’s medieval treason laws will be examined. > > In the aftermath of Friday’s terror attack on London Bridge in which two people were killed, Mr Johnson said: “Our treason laws must be updated to deal with transnational terrorist groups.”

Britain’s outdated laws constrain action and were written before modern technologies were invented, according to Boris Johnson and terrorist groups in the UK and abroad are exploiting legal loopholes in the law.
