"Scandinavian governments have spent millions of dollars on a campaign to remove me from power," he said on the station Kol Israel.
"Western governments, but mostly Scandinavian...They know perfectly well why they prefer Buji and Livni to me," he added, referring to his opponents.
In a separate interview with Rega Radio he was reported to have said that "foreign governments, specifically Scandinavians, are part of a worldwide campaign to topple me", according to a translation posted on Twitter by Israeli blogger and journalist Tal Schneider.
Sweden in particular has had strained relations with Israel in recent months after becoming the first western European country to formally recognize the state of Palestine.

The minister recently met with the Palestinian leader Mahmoud Abbas in Stockholm and this week held talks with with Palestinian Ambassador Hala Husni Fariz Odeh.
"Our relations with Sweden are deep, long lasting and have been strengthened further by the recognition of Palestine and the historic visit by President Mahmoud Abbas [to Sweden]," Odeh told Swedish news agency TT after their discussions.
