Transparency of Lobbying, Non-Party Campaigning and Trade Union Administration Bill

That was discussed at length in the debate on the previous group of amendments and I refer the hon. Gentleman to my remarks in that debate. Clearly, we want to ensure that there is confidence in the names and addresses that trade unions use for the membership lists. There is agreement on both sides of the Committee that it is important that membership lists are accurate and up to date. That is an existing responsibility and duty on unions. The membership audit certificate will provide confidence in the list. It is much more proportionate for smaller unions, for which it is much easier to keep details up to date—smaller unions have fewer than 10,000 members, whereas some of the larger unions have more than 1 million members—to provide an assurance themselves. However, to have the credibility required for the larger unions, we must have that independence, which is where the assurer comes in.
