Turkey, which has sought to join the European Union since the 1960s, has long seen Britain as one of the most enthusiastic supporters of its troubled bid.
But following Britain’s June vote to leave the bloc, both sides are now looking to bring a new dynamic to relations, with London seeking to firm up post-Brexit trade deals with non-EU states.
May’s spokeswoman said increased security cooperation, especially on aviation, and a new trade relationship post- Brexit would top the agenda at the talks.
Following the failed coup, Turkey’s relations with the EU have become strained, with Brussels sharply criticising the extent of the ensuing crackdown, and Ankara deploring Europe’s failure to show solidarity.
The spokeswoman emphasised that there were no issues May would steer away from, including human rights and freedom of the press.
“The Prime Minister’s approach is quite clear – she thinks it’s important, and in the UK’s national interest – to engage with Turkey on a range of issues – from defence and security cooperation to capitalising on trade opportunities,” she said.
