Greece should pay back its debt load to international creditors after serving Greek people's fundamental needs first, Panos Kammenos, head of the newly-founded nationalist Independent Greeks party, said Friday ahead of the May 6 general elections.

In a speech at his party's final rally under the Acropolis hill,Kammenos accused the conservative and socialist coalition partners of New Democracy and PASOK that support the bailout deals with international lenders to resolve the two-year Greek debt crisis, of condemning Greeks to poverty with the ongoing harsh austerity.

"We will pay back our dues, when we will be able to do so, not under such pressure...They call us dangerous, but we are just independent Greeks...We are dangerous for those who sell off Greece," Kammenos said.

He called on Greek voters to support his party, resist further salary cuts, tax increases and the privatization of public assets that critics call a sell off and "take their destiny into their own hands."

Founded as a splinter anti-austerity and anti-bailout party from the main Right New Democracy party this year, the Independent Greeks could garner some 10 percent during Sunday's polls, according to pollsters.

Kammenos has not excluded the prospect of supporting an anti-bailout coalition government formed mainly by Leftist parties, if New Democracy and PASOK will not win parliamentary majority, as opinion polls showed, and will fail to clinch new pro-reform coalition partners.

He argued that the next government can overcome the debt crisis that threatens Greece with disorderly bankruptcy since late 2009 focusing on solving chronic problems, such as corruption and waste of funds, rather than continuing on the austerity path that has fuelled recession.

The pro-bailout forces reply that such rhetoric and way of thinking is dangerous, since adds political instability to the financial woes, alarms lenders and international financial markets and could lead Greece to default and out of the eurozone.
