General elections were held in Turkey on 22 July 2007 to elect 550 members to the Grand National Assembly. Originally scheduled for November, the elections were brought forward after parliament failed to elect a new president to replace Ahmet Necdet Sezer. The result was a resounding victory for the incumbent Justice and Development Party (AKP), which won 46.6% of the vote and 341 seats. The party's leader Recep Tayyip Erdoğan was consequently re-elected as Prime Minister of Turkey. The opposition Republican People's Party (CHP) came second with 20.9% of the vote and took 112 seats. The Nationalist Movement Party (MHP), which had failed to surpass the 10% election threshold in the 2002 election, re-entered parliament with 14.3% of the vote and 71 MPs. The election was fought mostly on Turkey's debate over laïcité that had been perceived to be under threat from the AKP's nomination of Foreign Minister Abdullah Gül, an Islamist politician, for the Presidency. Developments in Iraq, secular and religious concerns, the intervention of the military in political issues, European Union membership negotiations, the United States and the Muslim world were other main issues.

The Grand National Assembly of Turkey, usually referred to simply as the TBMM or Parliament, is the unicameral Turkish legislature. It is the sole body given the legislative prerogatives by the Turkish Constitution. It was founded in Ankara on 23 April 1920 amid the National Campaign. This constitution had founded its pre-government known as 1st Executive Ministers of Turkey in May 1920. The parliament was fundamental in the efforts of Mareşal Mustafa Kemal Atatürk, 1st President of the Republic of Turkey, and his colleagues to found a new state out of the remnants of the Ottoman Empire.
