I think that's not the detail here. It would be more accurate to look at Simsek's roots and affiliations. RTE had accused KK of making deals with British loan sharks for 3 months, but he seems to be turning in the same direction.
Of all the AK party affiliates, the two that most represent the anglo-american establishment is Ali Babacan and Mehmet Simsek. These guys push and work towards the interests of the UK and US within Turkiye.
