Caroline Lucas tells the same programme she wasn't advocating "one, big overall pact", but rather that the two parties should consider ways to work more closely together to defeat the Conservatives. She says that when "progressives" fight against each other they allow the Conservatives to come through the middle and win.

Ms Lucas adds that the public is fed up with politicians "beating the life out of each other" and says that where there are areas where Labour and the Greens can agree, they should collaborate.

It's the heart of the political conference season and the Greens are down in Bournemouth this weekend. The party's MP, Caroline Lucas, who represents Brighton Pavilion, wrote an open letter to Jeremy Corbyn during the Labour leadership contest saying for the first time in her life the party could be led by someone who dares to stand up and demand radical change.

She said he should think about grassroots electoral pacts with her party - but Phélim MacCafferty, a Green councillor in Brighton and Hove, tells the World at One now is not the time for an alliance with Labour. He said Labour has not necessarily changed despite its new leader.

Two things are very clear now: first, there is a broad campaign that's been established by groups on the 'leave' side and UKIP is at the heart of that. It's called 'leave.eu, external'.

They're the ones who will be sending leaflets to your house, setting up public meetings and trying to friend you on Facebook. The man who is putting big money up for that, UKIP donor Arron Banks, doesn't want a single face to lead. Nigel Farage sees it differently and it's clear to me after having heard that speech that Nigel Farage is the de facto leader of that campaign. 

Second, that is going to be a problem for some on his own side, including some in his own party. He's been criticised for sounding too angry in the past. Some worry he's too divisive to ensure the 'leave' campaign wins. After the speech one senior UKIP figure told me the campaign must be "positive".

To be fair to Nigel Farage he talked of a "big, positive message". The test for him will be can he maintain that in the months ahead.

Addressing the party faithful at UKIP's annual autumn conference, leader Nigel Farage says the party "owns" the issue of immigration.

Nigel Farage arrived on stage to the song The Final Countdown - sung, yes, by a band called Europe. It highlighted this party’s central focus now.

More than two decades on from its birth, UKIP now eyes the challenge that motivated its foundation: leaving the European Union, in the referendum on the issue the prime minister has promised before the end of 2017.

Mr Farage told activists they must “summon all the heart and energy to winning" the vote. After devoting 20 years of his life to his party he said, the referendum campaign now needed to come first.

Eurosceptic groups, he claimed, had often been “run by egomaniacs” and that had to stop. The ‘leave.eu’ umbrella group, which Nigel Farage endorsed, would ensure this happened he said.

UKIP's Tim Aker says the polls have narrowed and a victory for the 'Leave' campaigns is achievable. Is Farage right to focus the party solely on the EU? Mr Aker says the issue has motivated Mr Farage for the past two decades, and adds that Britain's membership of the EU is "the fundamental question" of government.

Asked about reports that UKIP's only MP Douglas Carswell was in the press room reading the Guardian newspaper while Mr Farage was on his feet addressing the party faithful, Mr Aker says "you'll have to speak to him about that".

The Daily Politics

BBC political correspondent Tom Barton tells the Daily Politics there was a good atmosphere in the hall, with standing room only. Nigel Farage's speech pleased the rank of file, he adds. He says the UKIP leader was very clear the party has one thing to do and that is to win the referendum - and to do so by talking about immigration.

Tom Barton speaks to some of the young activists, who give their reaction to the speech. Flo says it was "truly inspirational" and got everyone motivated while another says he was "really impressed".
