Ukip leader Nigel Farage addressed the Master Investor show in London on Saturday (25 April), telling the audience that an Australian-style points system would benefit British industry.
Farage said his party offers a vision of "dynamic, self-confident country that believes in spirit of enterprise," and said Britain needs migrants "who have got trades and skills".
"We want migrants who bring with them health insurance, not a criminal record. I want immigration to be a positive, both socially and economically, and only by having an Australian-style points system can we achieve that," he said.
According to the "small business" section of its manifesto, Ukip says it "will do everything we can to help our small businesses compete in Britain and the global market".
Earlier this week, Farage said he prefers immigrants from Australia or India to those from Eastern Europe as they were "more likely to speak English, understand common law and have a connection with this country than some people that come perhaps from countries that haven't fully recovered from being behind the Iron Curtain".
On Friday (24 April), Farage told the Daily Telegraph that he had been prescribed Temazepam for a serious back condition to help him sleep, but is fit to fight the rest of his general election campaign. He added that was receiving hospital treatment twice a week.
He told the BBC that he is attending a private hospital twice a week as he does not have time for NHS appointments.
