Scotland Bill

I appreciate that the clause will not apply to the next Scottish election, but there are difficulties in Aberdeen where we have the forthcoming vote on AV and a vote on the Scottish parliamentary elections, which require two ballot papers. Sadly, one of the Liberal Democrat councillors died recently, as a result of which a by-election is also likely to be held on 5 May. The electorate in Aberdeen are thus looking at four separate polling formulae under different systems. The Minister used the word ““streamline”” earlier, so will he help me by explaining how we are going to streamline the elections in those sorts of circumstances?
