Marine Le Pen has said she has yet to secure all the funding she needs for her election campaign
The National Front leader, who is running in second place in the presidential race according to opinion polls, repeated her complaint that French banks were refusing to lend her money.
Speaking on Europe 1 radio after a visit last week to Moscow where she met President Vladimir Putin, she said she did not have any financial backing from Russia, nor from any Russian financial institution, but that she was trying to get a loan from a foreign bank.
She said: "I have to. I'm prevented from borrowing from French banks so now I am being told off for asking for a loan from a foreign bank.
"What am I supposed to do? … The French banks have lent to all the presidential candidates except for me."
One French bank, Societe Generale, has said it does not lend to any political parties.
The other main banks have declined to comment on the subject.
