Just hours before he addresses Ukip's annual conference, Nigel Farage has revealed he has not yet written his keynote speech.
He told LBC Radio: "I've been so busy this week I haven't yet had time to even sit down and write the speech, that's going to happen at lunchtime. I'll work it out later."
Asked about Ed Miliband's recent conference speech, the Ukip leader said there was not "a great deal of passion, or fire, or belief or connection" in the Labour leader's delivery.
Nigel Farage has claimed Labour have overseen the emergence of a fraud-ridden postal voting system in northern English constituencies "which would not be out of place in a country like Zimbabwe".
Writing in the Independent, the Ukip leader says Labour's dominance of northern England "has resulted in the emergence of a postal vote system rife with fraud and intimidation".
Ukip are holding their annual conference today in the Yorkshire town of Doncaster, a move Mr Farage describes as "parking our tanks on a rival party's lawn".
Ukip could take a number of seats from Labour in next year's general election, research by the University of Nottingham showed.
Vulnerable areas include:
- Shadow women's minister Gloria de Piero's Ashfield constituency.
- Retiring veteran Austin Mitchell's Great Grimsby
- Sarah Champion's Rotherham, where Ukip came second in a recent by-election.
- And Plymouth North View and Dudley North.
The UK Independence Party (Ukip) will directly try to capture the "blue collar" vote as they kick off their annual conference later today.
Ukip will outline plans to help low-paid workers by overhauling income and capital gains taxes, and set out reforms for the NHS.
It will also pledge to transform the way military veterans are treated by guaranteeing long-servers a job in the police, border force or prison service when they return to civvy street.
Nigel Farage's party are holding their conference in the town Labour leader Ed Miliband represents, Doncaster.
Mr Farage who will fight South Thanet, Kent, in next May's election, is expected to use his keynote speech this afternoon to make a "full frontal assault" on the Opposition, claiming it has failed the people it was founded to represent.
The leader of UKIP, Nigel Farage, says he is preparing to take his fight for the votes of Labour supporters into the heart of the Labour leader's constituency.
UKIP's annual conference opens in Doncaster tomorrow - the town represented by Ed Miliband:
Amjad Bashir, one of three Ukip MEPs in the Yorkshire and the Humber region, said his party was 'overjoyed' with the result:
It shows the hard work that we've put in. We've not been afraid to go out to the public, be asked difficult questions and answer those difficult questions.
We've also listened and other parties have failed to do that.
The businessman from Leeds also said his election showed his party is not a racist organisation:
Here I am, of Asian birth, of Asian parentage, Muslim, and I have been selected by this so-called racist party. It disproves that completely.
The party, in selecting me, I was voted in, it was a democratic process where the whole party nationally voted for me. I got the second highest number of votes and, therefore, I was selected for the area.
Ukip topped the poll in the Yorkshire and the Humber region with more than 400,000 votes.
Rotherham, where the party did well in Thursday's council election, was one of the earliest to see the party come in first. It was followed by others including Wakefield, York, Selby and North East Lincolnshire.
Roger Helmer, the Ukip MEP for the East Midlands, is to fight the parlimentary by-election in Newark next month.
He has been out in the constituency today speaking to voters about the seat he will contest instead of party leader Nigel Farage who said his candidacy would be a distraction.
The seat was vacated by former Tory MP Patrick Mercer who resigned after a cash for questions scandal.
The by-election will be held on June 5.
The Conservatives have selected Robert Jenrick to try to retain the seat after Mercer's resignation while Labour's candidate is Michael Payne.
The Liberal Democrats are expected to announce their choice in the coming days while the Buss Pass Elvis party are also likely to announce their runner.
UKIP's Yorkshire and North Lincolnshire candidate for the European Elections says the party should be included in televised debates in the lead up the the General Election.
Jane Collins says the party deserve the opportunity to share a stage with the major parties:
A Lincolnshire UKIP councillor's denied making offensive and politically incorrect comments about immigrants. Victoria Ayling says a video of her saying she wants to "send the lot back" actually refers to people who are living in the country illegally. Michael Billington reports.
