This general election seems to have more riding on it than ever and the discussion around tactical voting has been a prevalent and thought-provoking subject.
Many polling experts believe that if people abide by tactical voting then the some Tory held seats could swing in the favour of the Labour Party or the Liberal Democrats
Around 18 seats across the country could switch but it won't work in every seat that's why websites set-up by pro-EU activists like Remain United and Tactical Vote have put together informative guides, detailing how people should vote if they want to oust their Tory MP.
Amazingly one seat that could change hands is Boris Johnson's in Uxbridge and South Ruislip, where the prime minister holds a lead of just nine points, according to a recent YouGov poll.
Logically this would suggest that the next best candidate, who is Labour's Ali Milani, could win if enough people vote for him but there is a potential spanner in the works.
As pointed out by George Eaton of the New Statesman the estimated votes for both the Lib Dems and the Green Party is... Nine points.
If this were to happen on Thursday it would hand the seat back to Johnson, whereas if people vote tactically it could be an entirely different story.
Eaton's tweet has since gone viral with many sharing it as a plea to the people of Uxbridge and South Ruislip to use their heads if they want rid of Johnson.
Even Ali Milani has made a plea to the people he could be potentially representing come Friday morning.
Johnson has only held the seat since 2015, having previously been the MP for Henley before becoming Mayor of London in May 2008.
But the prime minister isn't the only prominent Tory whose seat is looking shaky.
Former Brexit secretary Dominic Raab, reportedly only holds a slim majority with the Lib Dems potentially poised to take the seat.
