This wonderful article from the BBC is outstanding for AS students of UK politics. It tracks what we can expect to see in the main parties manifestos so far. This in itself can be used as good evidence for party policies – especially if you compare these policies to what you have learnt about traditional party ideology.

However, this is also useful as evidence to assess the extent of the threat of UKIP. The actual threat of UKIP may remain minimal (see the earlier blog post following their first by-election success), the impact that they have had on the main parties, especially the Tories, has been marked.

It also demonstrates the impact of the Fixed Term Parliament Act; knowing the date of the election well in advance has moved the electioneering further forward than it usually is, therefore useful evidence for the UK Constitution topic.
