The first past the post system can lead to a lot of non-contests when it comes to the General Election. So which west London results should you look out for?
According to the latest predictions from the academics at Election Forecast, both Harrow East and Ealing Central & Acton are set to be too close to call when the results start to be announced in the early hours of Friday morning (May 8).
Labour is attempting to take both of these seats from the Conservatives with the latest predictions showing that the two parties are tied on 41% of the vote in Harrow East and 38% in Ealing Central & Acton.
Only 10 out of the 632 constituencies in Great Britain are currently on level-pegging so these two declarations are definitely ones to tune in for.
Harrow East's results are expected to come in at around 4am with Ealing Central & Acton's expected an hour later at 5am.
The only other west London seat that looks as though the result will be close is Brentford & Isleworth where Labour lead the incumbent Conservatives by four points. The declaration is expected at 5am.
