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

Is there not a legal contradiction in the Bill? A trade union has a duty under the Data Protection Act to keep in its records, but not to divulge, personal and private details relating to each member. If the Bill is passed, it will give the certification officer, the certification officer’s staff and the new assurers access to that information. That is a huge contradiction and I believe that it contravenes European law. Should we not consider that at the first possible opportunity?
