Prime Minister May's spokeswoman says both countries are expected to agree to a 'strategic security partnership.'
UK Prime Minister Theresa May will meet Turkish President Recep Tayyip Erdogan and Prime Minister Binali Yildirim on Saturday to discuss trade and security, her spokeswoman said.
A day after meeting US President Donald Trump, May will travel to Ankara to launch a joint working group to prepare the ground for a new trade relationship after Brexit.
Her spokeswoman said May and Erdogan would discuss two key themes,
"[They] will be discussing a new trade relationship following the UK's exit from the EU," and "they are expected to agree to ... a strategic security partnership."
May's government is keen to start laying the groundwork for trade agreements for when Britain leaves the European Union - a process that will take at least two years after triggering the formal divorce talks by the end of March.
The United Kingdom was the second-largest destination for Turkish exports in 2015, buying $10.6 billion in goods, according to IMF trade data. Only Germany imports more from Turkey.
