UK By Elections

  • By-Elections often alert a Government to change its path.
  • By-Election betting has grown over the last twenty years with the best betting sites offering a range of markets. 
  • The Chester and Stretford & Urmston By-Elections will take place in December 2022.  

Stretford and Urmston By Election

The Labour Party got 60% of the vote in the seat at the 2019 General Election. The bookmakers have Labour at a very short price to hold the seat at the By-Election.

Day Of The Week

In the United Kingdom, the majority of General Elections and By-Elections are held on a Thursday.

Why are By Elections Held?

A By-Election is held when a parliamentary seat becomes vacant in between General Elections. 

The voting for a new MP allows that parliamentary seat (Constituency) to have representation in the House of Commons. 

The reasons  By-Elections take place could be for any of the following reasons:

  • Death 
  • Resignation
  • Bankruptcy
  • Moves to the House Of Lords
  • Convicted of a criminal offence

Until the election is held the MP from the neighbouring constituency looks after the vacant seat. 

By Election Betting

The best betting sites that feature on will offer By-Election odds. 

There is normally at least a month when prices are available for the candidates. 

The odds will fluctuate with media reporting every gaffe made. 

Only twice since the 1980s has the party in government won a By-Election (1982 Mitcham and Morden & 2021 Hartlepool).

The Government of the day normally loses By-Elections with voters giving them a bloody nose as a protest against their Westminster policies. 

The Biggest By Election Swing

In 1982 a swing of just over 44% secured victory for the Liberal Party in Bermondsey which had been a safe Labour seat.

West Lancashire By-Election

The 2019 General Election saw the Labour Party hold the seat albeit with a reduced majority. 

The Conservatives did better in 2019 but could not replicate other successes they made in the north. 

Both the Brexit Party and the Liberal Democrats between them took around 10% of all the votes.

There will be no Brexit Party in this By-Election so you would expect the Liberal Democrats to increase their support. 

However, it is likely that Labour will increase their hold on the West Lancashire seat without too much bother. 

The West Lancashire By-Election is likely to be held in Autumn 2022.

2019 West Lancashire General Election Result

Party Votes Percentage
Labour 27,458 52.10%
Conservative 19,122 36.30%
Liberal Democrats 2,560 4.90%
Brexit Party 2,275 4.30%
Green Party 1,248 2.40%
