Prime Minister David Cameron is likely to win a May 7 national election and form a minority government, but his grip on power could be so tenuous that Britain will hold a second ballot this year, the leader of the UK Independence Party (UKIP) warned.
Opinion polls indicate neither Cameron's Conservatives nor the opposition Labour Party will win an overall majority in the 650-seat parliament as millions of voters turn to Farage's anti-EU UKIP party and the separatist Scottish National Party (SNP).
The closest British election in at least a generation has flummoxed seasoned politicians and City of London financiers who are pouring over opinion polls and Westminster seat predictions to see who might rule the world's sixth largest economy.
"The Tories (Conservatives) are going to be the biggest party," Farage, who is running for election in the South Thanet constituency in southern England, told Reuters in an interview. "You probably get a minority government."
In the February 1974 election, Labour's Harold Wilson won the most seats but no overall majority and led a minority government for a few months before calling another election in October 1974 when he won a tiny majority.
"In a situation when nobody could form an effective majority, the demands for electoral reform become huge," he said, adding that Britain's so called first-past-the-post winner-takes-all system would lose legitimacy if it failed to provide stable government.
BREXIT?
Opponents say Farage is a master orator who offers insecure voters an outdated vision of an imaginary Britain that never was. Some UKIP members have been publicly reprimanded or expelled for a range of racist and sexist comments.
In 2013, one UKIP member of the European Parliament described women at a political meeting as "sluts".
Farage denied his party is racist, saying every party had "its idiots".
Farage played down expectations of a massive breakthrough for his party on May 7, however, but said it needed to get a "respectable number" of seats to use as a spring board for the future.
Its real breakthrough would occur in 2020 after it had steadily built up confidence at local level across the country, he predicted.
"2015 is just the beginning of the journey for UKIP," Farage wrote in his 305-page book, The Purple Revolution, which was published this month. Purple is the colour UKIP uses on its party branding.
"I am already thinking of 2020. I genuinely believe that UKIP can be a very major party in that election, but not if our voters think we have sold out."
"CURTAINS FOR ME"
Farage, who has survived being run down by a car - when he admits he was drunk - a plane crash during an election stunt, and testicular cancer, said he would step down if he failed to win a seat in the British parliament.
"It is curtains for me," he said.
When asked what he would do outside politics, he declined to give a clear answer, but quipped that he was not right-wing enough to present the BBC motor show Top Gear, whose presenter Jeremy Clarkson has been suspended after the BBC said he was involved in a "fracas" with a producer.
A smoker who enjoys British beer and French wine, bets on horses and likes sea fishing, Farage dismissed local media speculation he might be ill.
After a pause to consider the question, he said: "I have lived a very clean lifestyle so I like to think I am reaping the dividends."
"I am fine. My body is a bit smacked up which makes it harder but no I am fine. I am fine. Fit as a flea."
