Political Parties and Elections Bill

Does the hon. Gentleman not accept that any money that finds its way into the political fund of a union affiliated to the Labour party or any other party has done so only after the union has collectively voted to set up or continue a political fund and only after individual members have used, or not used, the procedure for individually opting out? I support the general concept of a cap on donations, but surely the hon. Gentleman is doing precisely the opposite of what he proposed—he is bringing forward one element of the package without resolving the key issue of the status of donations from trade unions, which I maintain should not be captured by the limit.
