What if someone has been politically active in the past, will it affect clearance?
A. The Security Service is only likely to have a record on someone as a political activist if they have been involved with an organisation which advocates, or has in the past advocated, the overthrow of Parliamentary democracy by political, industrial or violent means. If in any doubt, details should be declared on the security questionnaire form and the candidate will be given a chance to explain the situation. Suitability for CTC clearance will be decided on the overall picture and not on one isolated piece of information.
