London Mayor Boris Johnson has defied Prime Minister David Cameron urging the cabinet ministers to join the campaign to leave the EU.
Johnson said he is seeking to change the minds of the majority of cabinet ministers who are in favor of voting to remain in the EU in a referendum slated for June 23.

"People should look at the arguments. I have huge respect for what the Prime Minister is saying. But people I think should think about the arguments," Johnson told the Telegraph.
He dismissed the argument that a "leave" vote could spark last-ditch talks to achieve a better settlement for Britain inside the EU, resulting in a second referendum, AFP reported.
He also stressed that there could be no other referendum. Last week Johnson argued that the EU "only really listens to a population when it says No."

The statement prompted Cameron to tell parliament on Monday that the idea of a second referendum was one "for the birds."
Opinion polls reveal differed outcome of the referendum, with the uncertainty sending sterling to a seven-year low against the dollar this week.
The latest poll, published on Friday by ORB for the Independent newspaper, showed support for the "out" campaign had risen to 52 percent from 48 percent from a month ago, while support to stay in the EU had fallen to 48 percent from 52 percent.
