Officers Linked To Political Parties

I submitted a request similar to this recently. I was looking to see if a full list of police officers and police staff who are registered as having notifiable memberships could be listed? Previously it stated those belonging to loyal orders.

Request 1
On this occasion could you please provide me with a list of officers who are members of a political party?

Request 2
Can you provide a list of political parties and the number of officers linked to each?

Request 3
Again, can this be done in terms of rank, showing the number of officers linked to political parties from the lowest ranking officer to highest?
