Trade Union Bill

I am grateful to the hon. Lady for allowing me—unlike the Secretary of State—to intervene. Everyone who heard the Secretary of State’s contribution will know that he cited the example of Northern Ireland, stating that what was good enough for Northern Ireland was good enough for the rest of the country. In particular regard to the political fund, trade union members in Northern Ireland have had to opt in, and that has been the case for over 60 years. Will the hon. Lady clarify what percentage of trade union members in Northern Ireland have opted in to the political fund?
