Fixed-term Parliaments Bill

I wonder whether my noble friend recalls that not only the noble Lord, Lord Wills, but all his political colleagues in another place promoted that legislation in terms precisely of the Political Parties, Elections and Referendums Act and the control of the expenditure of political parties. Why have the noble Lord and all his colleagues changed their minds? I notice that the noble Lord, Lord Bach, is back in his usual place. Perhaps he would like to explain why he has changed his mind, having teased my noble friend on this point.
