Stop Convicted Terrorists becoming Councillors and MPs in Britain

Background

I want the British Government to bring in laws that prevent convicted terrorists who have committed terror offences abroad to not be able to become Councillors or MPs.

Additional details

Anyone who has shown they have no regard for Britain and British people do not deserve the right to try to implement change. Therefore I want a debate and to bring it to the attention of the world some of us won't put up with it!
