Erdogan to be sworn in for third term as Turkish president

Recep Tayyip Erdogan is set to be sworn in Saturday for a third term as president after winning a historic runoff election to extend his two-decade rule, as Turkey's economic woes worsen.

The inauguration in parliament will be followed by a lavish ceremony at his palace in the capital Ankara attended by dozens of world leaders.

Turkey's transformative but divisive leader won the May 28 runoff against a powerful opposition coalition, despite an economic crisis and anger over a February earthquake that killed more than 50,000 people.

Erdogan won 52.18 per cent of the vote while his secular rival Kemal Kilicdaroglu scored 47.82 per cent, official results show.

Turkey's longest-serving leader faces significant immediate challenges in his third term, including the slowing economy and tensions with the West.

"From a geopolitical point of view, the election will reinforce Turkey's recent pursuit of an independent foreign policy," said Matt Gertken, chief geopolitical strategist at BCA Research.

"This policy aims to extract maximum economic and strategic benefits from eastern and autocratic states while still preventing a permanent rupture in relations with western democracies," he said.

"Tensions with the West will likely increase again," Gertken added.

Azerbaijan's president Ilham Aliyev, Iran's vice president Mohammad Mokhber, Hungary's right-wing prime minister Viktor Orban and the speaker of the lower house of Russia's parliament, Vyacheslav Volodin, are among the foreign guests expected at the inauguration.

Armenia's prime minister Nikol Pashinyan will also be present, his office said, the latest sign of a thaw between the two arch foes.

Addressing the country's economic troubles will be Erdogan's first priority, with inflation running at 43.70 per cent, partly due to his unorthodox policy of cutting interest rates to stimulate growth.

The president is due to unveil his new cabinet on Saturday, with media speculating that former finance minister Mehmet Simsek, a reassuring figure with international stature, could return.

A former Merrill Lynch economist, Simsek is known to oppose Erdogan's unconventional policies.

He served as finance minister between 2009 and 2015 and deputy prime minister in charge of the economy until 2018, before stepping down ahead of a series of lira crashes that year.

"Erdogan's government looks like it will pursue an orthodox stabilisation programme," said Alp Erinc Yeldan, professor of economics at Istanbul's Kadir Has University.

"What we see now is that the news about Mehmet Simsek and his team is greeted with enthusiasm by the markets," he told AFP.

Turkey's new members of parliament were sworn in on Friday in its first session after the 14 May election, with Erdogan's alliance holding a majority in the 600-seat house.

Kilicdaroglu's future as leader of the CHP party remains in doubt following his defeat to Erdogan.

NATO allies are anxiously waiting for Ankara to green-light Sweden's drive to join the US-led defence alliance, before a summit in July.

Erdogan has delayed approving the application, accusing Stockholm of sheltering "terrorists" from the outlawed Kurdistan Workers' Party (PKK) which is listed as a terror group by Ankara and its Western allies.

NATO chief Jens Stoltenberg will attend Erdogan's inauguration and hold talks with him, the alliance said Friday.

Sweden's foreign minister, Tobias Billstrom, said on Twitter that "a clear message" had emerged at a NATO meeting in Oslo for Turkey and Hungary to start the ratification process.

His Turkish counterpart Mevlut Cavusoglu responded on Twitter: "A crystal clear message to our Swedish friends! Fulfil your commitments (and) take concrete steps in the fight against terrorism.

"The rest will follow."
