Two more top Turkish opposition politicians have resigned ahead of next month's general election after secretly filmed tapes posted on the Internet reportedly showed them having extramarital affairs.The resignations on Tuesday raised to four the number of far-right Nationalist Action Party politicians forced to withdraw from the June 12 elections. Two other politicians resigned last month after similar sex tapes emerged.
Party leader Devlet Bahceli says the tapes aim to harm his party and has suggested that Prime Minister Recep Tayyip Erdogan's supporters may be behind them.
Opinion surveys show the far-right party hovering close to a 10 percent support threshold that is designed to keep smaller parties out of Turkey's parliament.
