Nigel Farage says he wants to be PM by 2029 - despite admitting Reform might only get a few MPs at election - as manifesto launch gets off to tricky start with party's deputy leader wrongly claiming OBR watchdog has approved figures

Nigel Farage insisted he wants to be PM by 2029 today as he prepares to launch Reform's manifesto.

The Brexiteer said he was 'absolutely' aiming to be in Downing Street despite conceding that his party might only end up with a few MPs after the election.

The boast came as Reform's crucial day got off to a shaky start - with deputy leader David Bull wrongly claiming that the Office for Budget Responsibility watchdog has signed off its spending plans.

The insurgents are billing its proposals a 'contract' as Mr Farage says the public has lost faith in the term 'manifesto'.

The document is being unveiled in Merthyr Tydfil, Wales, as Reform tries to show that it is taking on Labour as well as the Tories.

Mr Farage said the location was chosen 'because it shows everyone exactly what happens to a country when Labour is in charge'.

It is expected to include commitments to slash £50billion off public spending, leave the European Court of Human Rights, and ban all 'non-essential' immigration. 

The party is also set to propose making St George's Day and St David's Day bank holidays, and abolishing the BBC licence fee. 

Interviewed on Sky News, Dr Bull was asked if Reform had shown its plans to the OBR and respected IFS think-tank.

'We have and we've spoken to top economists…' he replied.

Pressed by Kay Burley on what the OBR had said about the manifesto, Dr Bull said: 'I can't tell you what the OBR said because I didn't speak to them… '

Challenged on how he knew they had been consulted, Dr Bull said: 'Because I do, because we know that we've had due diligence across all our policies.'

When Burley probed whether he was sure about the OBR being asked, Dr Bull said: 'As far as I'm aware, yes.'

The presenter reminded him that he said the watchdog was 'definitely' consulted.

'OK, I'll go with definitely. We will have done,' he replied.

The OBR is legally prevented from assessing the policies of opposition parties. 

Speaking to BBC Radio 4's Today programme, Mr Farage said: '(The Conservatives) can't agree on anything, they're split down the middle, and we know what we stand for, we know what we believe in, and for democracy to function properly there needs to be a proper voice of opposition.

'And our plan – and this is our first big election as a party – our plan is to establish that bridgehead in Parliament and to use that voice to build a big national campaigning movement around the country over the course of the next five years for genuine change.'

Asked if he would seek to be PM at the next election - due by 2029 - Mr Farage replied: 'Yes, absolutely. I think the disconnect between the Labour and Conservative Westminster-based parties and the country – the thoughts, hopes and aspirations of ordinary people – are so far apart from where our politics is.'

Mr Farage claimed the idea that Donald Trump wanted to overturn a democratic election is a 'matter of opinion', adding: 'What happened on January the 6th should not have happened, of that there's no doubt whatsoever. Did he actually urge people to storm the Capitol building? No, he didn't.'

When pressed on the issue, he said: 'No, I don't approve of objecting to elections, even though I object to much of what's happening in our system, with postal vote corruption and many other things.'

Senior Conservative figure David Davis warned that Farage was 'trying to destroy' the Tories, as the party continued to see Reform eating into their vote.

He told Times Radio: 'Farage is trying to destroy the Conservative Party. That is his explicit aim.

'When somebody tries to burn down the golf club, you don't offer them membership, do you?'

Ex-Cabinet minister Robert Jenrick took his attack to Richard Tice, accusing the Reform chairman of being a Labour 'sleeper agent'.

Mr Jenrick added: 'I not only understand the frustrations of Reform voters, I share them.

'But a vote for Reform can only deliver a Labour one-party state that increases taxes and immigration.'
