A poll conducted by the Metropol Foundation found that Turkish support for President Recep Tayyip Erdogan rose sharply last month when Ankara launched a military incursion in northeastern Syria to expel the Syrian Kurdish People's Protection Units (YPG) from areas bordering its borders.

Support for Erdogan rose 3.7 percentage points to 48 percent in October, the highest since the presidential election in June 2018, which was surveyed before the domestic currency crisis raged last year, a poll published on Tuesday showed.

The percentage of non-supporters of the president fell 9.3 percentage points to 33.7%, the lowest since a coup attempt in July 2016. Some 18% of those surveyed did not respond to the vote or said they had no conclusive opinion.

Support for Erdogan has shrunk since a crisis triggered a 30 percent drop in the lira's value last year, with rising inflation, unemployment and a recessionary economy.

Ankara considers the YPG a terrorist organization and an extension of the outlawed Kurdistan Workers Party (PKK). The PKK has waged a revolt against the state since 1984, a conflict that has claimed about 40,000 lives.

Four of the five parties represented in parliament supported the military operation "Spring of Peace" and were opposed by the pro-Kurdish Democratic People's Party (PYD) and said it was aimed at supporting eroded support for Erdogan and his AK Party.

Ankara launched the military operation in northeastern Syria on October 9, days after a surprise decision by US President Donald Trump to withdraw troops from northern Syria following a call with Erdogan. The Turkish incursion drew international condemnation.

Turkey then reached separate agreements with Washington and Moscow to halt the military operation in return for YPG militants pulling away from the border into Syria.
