Keir Starmer and Recep Tayyip Erdogan are set to sign a UK-Turkey security and defense partnership on Wednesday on the sidelines of the NATO summit.
The pact will deepen cooperation on cyber threats, counter-terrorism and the defense industry, according to people familiar with the planned agreement.
The signing is expected during a meeting between the outgoing UK prime minister and the Turkish president, tying the deal to summit diplomacy among NATO allies.
