Mr Farage has said he is aiming for Reform to become the main opposition to Labour by the time of the next election.
His surprise announcement that he was standing in the election, after previously saying he would not, saw a jump in Reform’s poll ratings.
At the same time, he took over from Richard Tice as Reform’s leader and he has played a prominent role in the party’s campaign.
The former UKIP and Brexit Party leader has stood unsuccessfully to be an MP seven times, most recently in South Thanet, Kent, in the 2015 general election, when he finished second behind the Tory candidate.
Clacton was the first constituency to elect a UKIP MP in 2014, after former Tory MP Douglas Carswell defected to the party and triggered a by-election, which he won.
He was unseated by Conservative Giles Watling in 2017, who is fighting to retain the seat.
More than 70% of voters in the Essex constituency supported leaving the European Union in the 2016 referendum.
In 2019 Reform’s previous incarnation, the Brexit Party, stood aside in more than 300 seats previously won by the Tories, amid concerns it could split the pro-Brexit vote.
However, this time the party contested 630 seats across England, Scotland and Wales.
Fielding an almost full slate of candidates in Great Britain posed challenges for the party.
Reform has had to disown six of them over offensive comments since nominations closed.
The party has blamed the surprise announcement of a July election, as well as claiming a company it hired to conduct background checks on would-be candidates failed to carry out vetting before the election was called.
Two Reform candidates also defected to the Conservatives over what they said was a failure of the party’s leadership to tackle the issue.
However, it was too late to remove any of these candidates so they still appeared for the party on ballot papers.
