Sir Bob Geldof tells ITV News some "facts about fishing" as he goes head-to-head with Nigel Farage in an 'In and Out campaign-off' on the Thames.
The Boomtown Rats rocker urged voters not to listen to Remain campaigner Nigel Farage as he branded him a "liar" who "hasn't got a clue what he's doing".
"He's an opportunist of the worst kind," he said.
Alistair Darling has slammed the Leave campaign for creating a "flimsy and fraudulent" manifesto.
Speaking at a Remain event in Ashford, he said: "The Leave campaign has no idea no plan whatsoever. Any political party seeking an election on such a flimsy and fraudulent prospectus would've been torn to bits right now.
"We do know we will have years and years of uncertainty. Why on earth would we want to inflict that on ourselves all over again?"
Mr Darling quoted from Roberto Azevêdo,the head of the World Trade Organisation, who said it will take a decade to negotiate trade agreements and insisted "Britain's economy will be smaller and Britain's families will be poorer".
Making reference to the emergency budget that he was launching, he added: "There would not be one emergency budget, but one after another".
Former Chancellor of the Exchequer Alistair Darling has said an economic "explosion will follow" if Britain leaves the European Union.
He said: "Once you light a blue touch paper in our economy, you can never be sure where it'll end up. We do know an explosion will follow.
"Look at what's happening in the real world right now. Sterling is more volatile. Investment decisions are on hold. Almost $100bn has been wiped off the stock exchange in recent days.
"All of this will damage our investment and productivity", he added.
Labour MP Alistair Darling has said Britain is "stronger together, working together, working with, not apart from our closest neighbours and allies".
Launching the emergency budget alongside George Osborne, he added that Britain is "a gateway to Europe" as large international firms "want to invest and create jobs here".
Darling also credited EU regulations that has protected employees. He said: "Workers rights are protected too. Maternity and paternity pay, paid holidays, the right not to be discriminated against at work - it all stemmed from EU law."
George Osborne has said businesses would be "hard hit" if the UK decided to leave the EU.
Speaking at the launch of his emergency budget in Ashford, the Chancellor of the Exchequer listed the likely tax increases.
He said there would be a 5% increase on alcohol and fuel, and a similar rise in inheritance tax. There would be £2.5bn cut to the NHS, £1.2bn slashed off the defence budget, education spending will be down £1.5bn and the basic rate of income tax will increase by 10%.
Labour MP Alistair Darling has pleaded with voters to remain in the EU as it has helped "bring prosperity".
The former Chancellor of the Exchequer, who was sharing a stage with George Osborne, said: "For every £1 we put into the EU, we get £10 back in terms of benefits.
"It's benefits are unarguable and rather obvious - it's jobs. Membership of the biggest single trade market in the world has helped bring prosperity", he added.
The In and Out sides of the EU referendum have clashed at a flotilla protest to take back control of British waters on the Thames.
Nigel Farage, who is leading the Leave campaign, was greeted by Remain campaigner Sir Bob Geldof who blasted out the song "In With the In Crowd".
There were also reports the Remain craft had been targeted with water from a fishing boat's hose.
ITV News political editor Robert Peston said the emergency budget warning by Alistair Darling and George Osborne is a huge moment for the Remain campaign.
He adds that if they fail to stem the Leave momentum, the UK will probably vote to be out of the EU.
George Osborne has said quitting the EU is a "lose lose situation for British families" and "we should not risk it".
The Conservative MP highlighted the economic fears a potential Brexit has caused, and said "we don't have to chose this risky and damaging future for our country".
He said the leave campaign has "no plan and have admitted they just don't know what leaving looks like, but we do. Leaving is a leap in the dark that will put our children's future and our place in the world at risk".
The Chancellor of the Exchequer has said "quitting the EU would hit investment, hurt families and harm the British economy".
Speaking at the launch of his 'emergency budget', George Osborne said plans need to be in place in case the UK decides to leave the EU to "restore stability to the public finances".
He said the government would "almost certainly" need to raise taxes and cut spending in such circumstances.
