Parliamentary Voting System and Constituencies Bill

As in many of these issues, it is about whether there is a clear mark. If the elector marks the paper in such a way that it is not possible for the returning officer to work out what they intended, it clearly cannot count, so it comes down to whether they have expressed a clear preference. In the case that the hon. Member for Rhondda set out, it would be clear what they had done, so there would be no problem.
