LONDON -- Greece's debt problems may require further help from euro zone countries but Britain is not keen to be part of any further rescue, finance minister George Osborne said on Sunday.

"We certainly don't want to be part of any bailout of Greece, a second bailout of Greece," he told the BBC.

Osborne said Greece's lack of access to international debt markets was problematic since last year's international rescue was based on the premise that such borrowing would resume.

"There are some very difficult questions that Greece has to address now because the whole assumption when the euro zone put together a rescue package last year was that Greece could come back into the market next year and borrow."
