Local By-Election Review : 2015 – 2017 Parliament

Local By-Election Review : 2015 – 2017 Parliament

Harry Hayfield on whether they’re a pointer to Thursday

There have been 588 local by-elections during this Parliament in which a total of 1,029,887 votes have been cast. These are not virtual votes cast in opinion polls, or online, but physical votes in physical ballot boxes up and down the country. Overall these votes (and seat wins) have split as follows:

Con 30%, Lab 28%, Lib Dem 16%, UKIP 7%, SNP 6%, Green 5%, Ind 4%, Plaid 0.77%, Others 3%
Con 235 (-19), Lab 159 (-18), Lib Dem 89 (+39), UKIP 13 (-14), SNP 30 (+1), Green 8 (+4), Ind 26 (-3), Plaid 9 (+4), Others 30 (+1)

However, as we all know, there was a mass upheaval halfway through this Parliament with the European Union referendum, and it is interesting to note that in the 332 local by-elections following that referendum, the voting share (and seat wins) was:

Con 34%, Lab 27%, Lib Dem 18%, UKIP 6%, Ind 5%, Green 4%, SNP 3%, Plaid 1%, Others 2%
Con 148 (-6), Lab 81 (-22), Lib Dem 59 (+33), UKIP 6 (-9), Ind 15 (-5), Green 4 (+2), SNP 5 (-1), Plaid 5 (+3), Others 9 (+9)

Therefore in order to make sense of this sea change in politics and put it in the context of the general election, I will tally the votes cast in all the local by-elections both before and after the referendum, thus creating a midpoint by region and using that to calculate the number of seats that each party may win. I realise that this may upset some people but seeing as we have multiple polling organisations stating that (on the same day) the Conservative lead is in the range of 3% to 12%, then I believe my methodology has just as much validity as theirs
