In terms of electoral reform, there might also be a change in the European Elections.
In the beginning of March, there will be the second reading in the House of Commons on a bill to make provision for an open list system for elections to the European Parliament.
A LSE study from 2013 showed that such a change would mean that support for UKIP would decrease, and the overall vote share for the Conservative party would increase as voters could choose very Eurosceptic Conservatives instead of UKIP if they were to be sure that their vote would benefit a Eurosceptic candidate. Also, it should lead to candidates and MEP increasing their constituency work and building a stronger local profile.
Since this will probably benefit the Conservatives, I guess there should be a good chance of it being passed. I guess the opposition MPs in favour of general election reform would also see this as a step forward.
