Political Parties and Elections Bill

I fear the Minister may be losing his way. Although I disagree with his history lesson, which was somewhat more enjoyable than sitting on the Bill's Committee, despite that being enjoyable too, I welcome his concession on indexation. Will he outline the methodology for his approach in the Lords to overcome some of the problems of indexation that have been mentioned—such as the small increases—so that we do not have to come back to those issues, as we have had to do since the Political Parties, Elections and Referendums Act 2000, with the 25 per cent. increase, and can allow for the sensible increase the Minister proposes?
