A former Polish foreign minister has come under fire from the prime minister and political opponents for giving a U.S. magazine interview in which he allegedly said Russia's president offered Poland the opportunity to jointly carve up Ukraine in 2008.

Radek Sikorski, now the parliamentary speaker, was quoted as saying in Sunday's issue of Politico Magazine that Russian President Vladimir Putin "wanted us to become participants in this partition of Ukraine."

In a news conference on Tuesday, Sikorski was vague about whether he made those exact remarks and told journalists to refer to another interview he gave to a Polish media website.

Prime Minister Ewa Kopacz, who's in the same party as Sikorski, said she wouldn't tolerate him dodging reporters' questions on the issue, and political opponents want him fired.
