Ban anyone convicted of terrorism offences from standing for public office

Introduce a new legal disqualification so people convicted of terrorism offences (in the UK or abroad) cannot stand as candidates or hold elected office, including local councils.

This is needed because current local election disqualification rules focus mainly on recent imprisonment thresholds (for example, being sentenced to 3 months or more within the last 5 years) and therefore may not prevent individuals with serious historic convictions from standing today. The Electoral Commission notes that the returning officer cannot confirm whether a candidate is disqualified and candidates self-declare their eligibility when submitting nomination papers.
