Recep Tayyip Erdogan is arguably the most formidable politician since modern Turkey’s founding father, Ataturk.
After 11 years as prime minister, he was elected president in 2014 - but under a parliamentary system, in which his role should be largely ceremonial.
The fiercely ambitious Mr Erdogan is intent on changing that to a presidential system, which he says would make Turkey function more effectively, but which would also significantly increase his powers.
