My Lords, Amendment 34, moved by the noble Lord, Lord Faulks, was the subject of some debate at Second Reading, and the issue has since been referred to several times. I was not persuaded then that this is the right way to proceed and, having listened to a number of noble Lords speak in favour of the amendment, I am not persuaded now.
As we have heard, the Treason Act 1351 is still in force today, although it has been amended. I believe it was last used to prosecute William Joyce in 1945 after the Second World War. As the noble Lord, Lord Faulks, said, it has a somewhat chequered history. There is ample opportunity to prosecute British citizens, and those who are not British citizens, who commit acts of terrorism for a range of offences, using legislation that is already on the statute book.
