Nigel Farage's battle for South Thanet will go to a recount, according to senior Ukip sources.
The Ukip leader's targeted Kent seat has been a fierce three-way battle between Farage and his Tory and Labour rivals - and the party think it will go right down to the wire following a surprising exit poll.
A Ukip spokesperson said: "It's very tight, we'll see."
The same source predicted a win for former Ukip policy cheif Tim Aker in Thurrock.
But he said the projected outcome of the election would make a mockery of the electoral process, and said constitutional reform needs to take place.
He said: "The success of Ukip will be measured by how many second places we win, by vote share and by seats won.
"It's likely that 20% of the electorate will vote for Ukip and the Greens, and will get 2% of the seats.
"This is a travesty of democracy and must change."
At a rally earlier today Nigel Farage invoked Ghandi as he insisted Ukip support was "rock solid".
He told a rally in Broadstairs, Kent: ""First they ignore you, then they laugh at you, then they attack you, and then you win."
