Kent Police have confirmed that they are looking into an allegation of electoral fraud in the Thanet South constituency seat.
The leader of UKIP Nigel Farage temporarily resigned as party head over the weekend after he failed to win the seat. Instead, Craig Mackinlay, a Conservative became the Thanet South MP after last Thursday's General Election. He won 18,838 votes compared to Mr Farage's 16,026.
UKIP took control of Thanet District Council in following the local elections counton Saturday.
"Kent Police has received a report of electoral fraud. Inquiries are ongoing."
Kent Police are looking into an allegation of electoral fraud in Thanet South, the seat which Ukip leader Nigel Farage failed to win at the general election.
Nigel Farage's offer of resignation was rejected by UKIP members because of the success of his election campaign, according to a statement by the Chairman of UKIP has revealed.
As promised Nigel Farage tendered his official resignation as leader of UKIP to the NEC. This offer was unanimously rejected by the NEC members who produced overwhelmingly evidence that the UKIP membership did not want Nigel to go
The NEC also concluded that UKIP's general election campaign had been a great success. We have fought a positive campaign with a very good manifesto and despite relentless, negative attacks and an astonishing last minute swing to the Conservatives over fear of the SNP, that in these circumstances, 4 million votes was an extraordinary achievement. On that basis Mr Farage withdrew his resignation and will remain leader of UKIP. In addition the NEC recognised that the referendum campaign has already begun this week and we need our best team to fight that campaign led by Nigel. He has therefore been persuaded by the NEC to withdraw his resignation and remains leader of UKIP.
He may have lost his bid to become an MP, and even resigned as UKIP leader yesterday because of it - but Nigel Farage had time today to hail more successful UKIP colleagues. More than thirty of them have been elected as councillors for Thanet District Council in Kent.
Nigel Farage has officially stood down as the leader of the UKIP party.
During his speech at the Botany Bay Hotel in Broadstairs he criticised the first past the post voting system saying it was unfair for smaller parties.
Mr Farage said although today is tinged with sadness he feels happier than he has for years.
Suzanne Evans will be the new leader.
Nigel Farage is likely to step down as leader of Ukip if he loses his seat in South Thanet, creating a "real blow for the party", political journalist Isabel Hardman has told ITV News.
The assistant editor of The Spectator has heard from "a very good source" that the party have not won the constituency in Kent.
Hardman said: "If he doesn't win that seat then he will have to step down as Ukip leader because he said he would. In that case Ukip would be pitched into a leadership battle which would be very difficult for the party because Farage is a magnetic figure who has held the party together.
"Even though he has some very impressive people behind him, they're not quite the same as Nigel Farage - so it would be a real blow for the party."
Earlier, Mr Farage gave aninterview to ITV News in which he attacked the press before walking off.
A senior UKIP source refused to rule out defeat, saying it was still a very tight contest in South Thanet. He said he believed the exit poll putting Ukip on winning two seats was wrong, adding that the Eurosceptic party was poised to come second in a number of constituencies.
In Margate, Al Murray, who is standing in the guise of his patriotic character the Pub Landlord for his newly-formed party, the Free United Kingdom Party (FUKP), arrived at the count in front of a battery of photographers.
Dressed in his trademark burgundy blazer, Oxford-educated Murray spoke about rumours Farage had lost in South Thanet, saying: "Well, then we are all walking with history tonight."
He said he would welcome Mr Farage into his pub if it turns out he has lost, adding: "If he's drowning his sorrows tomorrow, then I will say, 'Oh well, mate, better luck in 2020'."
Nigel Farage said it would be "curtains" for him as UKIP leader if he lost South Thanet. The suggestions at the count are that the Tories have won. If he does stand down as leader, it might not be the end of his career. He's stood down as leader before, then came back. But UKIP would face an uncertain future without him at the helm.
Nigel Farage has finished runner-up in Thanet South, losing out to Tory candidate Craig Mackinlay by almost 3,000 votes.
Mr Farage, who has vowed to resign as leader if he failed to enter the Commons, polled 16,026 votes.
But the Tory candidate did better, winning the backing of 18,838, with Labour third.
Nigel Farage has insisted he has "never felt happier", with a "weight lifted off his shoulders".
