The Foreign Secretary, in his reply to the initial question from my right hon. Friend Mr Ellwood, talked about the PKK threat to Turkey across its southern border. When I was there four weeks ago, we could see no evidence of that. What evidence does the Foreign Secretary have for there being a threat across the southern border? The PKK was undoubtedly responsible for giving the SDF the capacity to help stop ISIS in 2014, but since then, from what I could see, particularly with the agreement to allow joint Turkish and American patrols 5 km into the area it controlled over the border, it was bending over backwards to make sure there was no threat or provocation to Turkey from Syria in the south.
