Constitutional

Perhaps the least-known impact on the province will come through constitutional change. A reformed House of Lords and changes in the voting system would both have an effect on the local electorate.

Committing to an end in double jobbing, each successful DUP candidate will step down from the Assembly “within weeks”, except Peter Robinson.

Ministers and Whitehall departments should be cut by a third, the party says.

Alliance sits very much in the Liberal Democrat camp, supporting the alternative vote system, a written constitution and votes for 16 year-olds.

A hung parliament should be used to the province’s benefit, whether on the big political issues or at constituency level, according to the TUV.

A free Commons vote on reducing the voting age to 16 is also proposed.

Labour commits to banning MPs from lobbying, along with requiring approval for paid outside appointments.

Northern Ireland would continue to be supported by “unprecedented public funding” while the Calman Commission’s recommendations will be implemented in Scotland, which includes additional tax- raising powers. Wales could also expect a referendum on having more legislative powers based in Cardiff Bay.

Double-jobbing would end under a Conservative government. The West Lothian Question would be partly answered with new rules so that legislation referring specifically to England, or to England and Wales, could not be made law without the consent of MPs representing those countries.

As Prime Minister, David Cameron would attend Holyrood for questioning on a “regular basis”. No such commitment is made for Northern Ireland.

The Lib Dems say that parliament would meet for a fixed term rather than the PM calling an election while a fully elected House of Lords is also proposed.
