Corruption in Turkey is an issue affecting the accession of Turkey to the European Union. In 2014, Turkey was ranked 64th of 175 countries on Transparency International's Corruption Perceptions Index. The 1998 Türkbank scandal led to a no-confidence vote and the resignation of Prime Minister Mesut Yılmaz. Although Yılmaz was investigated by Parliament, a five-year statute of limitations prevented further action. On 17 December 2013, the sons of three Turkish ministers and many prominent businesspeople were arrested and accused of corruption.
