In a General Election where traditional voting patterns have been completely shaken up, it’s going to be harder than ever to accurately predict who’s in and who’s out.

We’ve put together some analysis of the Top 50 most marginal seats which oddly enough begins and ends with Conservatives looking to hold seats in Wales - starting with the Gower’s majority of just 27 votes and ending with Cardiff North’s 2,137. Unusually, it doesn’t look like the Tories will be short of seats in Wales – after their best performance since 1983 in the 2015 election, some polls are suggesting between 6 and 10 more gains this time.

There are also set to be upsets right across the country. Whilst the Lib Dem fightback looks overblown, UKIP has almost certainly collapsed, the Tories could make gains in Scotland and many Labour seats of up to 10,000 majorities are potentially at risk – these are unpredictable times for political nerds.
