Another lawmaker from Turkey's ruling party resigned on Tuesday over a high-level corruption scandal, further shaking Prime Minister Recep Tayyip Erdogan's grip on power.

Hasan Hami Yildirim had criticized the government for exerting pressure on the judiciary over the graft investigation, which has plunged Turkey into political turmoil just three months ahead of key elections.

A Turkish woman was detained after brandishing a shoebox in an anti-government protest over a sweeping graft probe that has ensnared allies of Prime Minister Recep Tayyip Erdogan, local media reported Monday.

The shoebox has become a symbol of the corruption scandal after police earlier this month found $4.5 million stashed in shoeboxes in the home of one of the suspects, the chief executive of Turkish state-owned Halkbank.

The political crisis engulfing Turkish Prime Minister Recep Tayyip Erdogan has cost the economy $100 billion, a top official said Monday, as financial markets rebounded from a massive freefall.

Deputy Prime Minister Bulent Arinc also fired off a new salvo against a powerful group that the government charges is behind a sweeping corruption probe that has shaken the very core of Erdogan's administration.

Turkey's embattled Prime Minister Recep Tayyip Erdogan was to address a political rally on Saturday in a bid to muster support after a fresh round of protests demanding that he step down over a spiraling corruption scandal.

The conservative prime minister, who has dug in his heels over the crisis that has led to the resignation of three ministers, was to speak in the southern city of Manisa later Saturday.

The European Union urged Turkey on Friday to address corruption allegations involving close government allies in a "transparent and impartial manner".

"I urge Turkey, as a candidate country committed to the political criteria of (EU) accession... to take all the necessary measures to ensure that allegations of wrongdoing are addressed without discrimination or preference in a transparent and impartial manner," EU Enlargement Commissioner Stefan Fule said in a statement.

Three lawmakers including a former minister resigned Friday from Turkey's ruling Justice and Development Party (AKP) amidst a high-level bribery and corruption probe ensnaring close government allies.

The ruling party is being directed by "arrogance," said one of the lawmakers Ertugrul Gunay, who was a former culture minister, at a news conference, adding that he was parting ways with the AKP.

Turkey's top court on Friday blocked implementation of a government decree ordering police to inform their superiors before launching investigations issued by public prosecutors, local media reported.

The government decree was introduced last week after police conducted raids targeting senior figures including the sons of ministers and businessmen as part of a fast-moving corruption inquiry.

The son of Turkey's prime minister will likely be the next target of a widening graft probe that led to a major cabinet reshuffle after three ministers resigned, Turkish media said Thursday.

Several newspapers said a bitter struggle between Prime Minister Recep Tayyip Erdogan and his one-time ally turned opponent Fethullah Gulen was set to become more venomous as the corruption scandal inches closer to the premier's inner circle.

The Turkish lira hit a fresh record low on Thursday following a cabinet reshuffle by Turkish Prime Minister Recep Tayyip Erdogan amid a huge graft scandal.

The lira fell to 2.1035 against the dollar on Thursday, after starting the day at 2.0914.

Turkish Prime Minister Recep Tayyip Erdogan on Wednesday reshuffled his Cabinet after three key ministers resigned over a sweeping corruption and bribery scandal that has targeted his allies and rattled his government.

Erdogan replaced Economy Minister Zafer Caglayan, Interior Minister Muammer Guler and Erdogan Bayraktar, the minister for the environment and urban planning. All three men's sons were detained as part of the corruption investigation. They all deny any wrongdoing.
