I am horrified at the appointment of the former prime minister David Cameron as foreign secretary. He demonstrably lacks two of the essential characteristics for that difficult role: skill as a negotiator and a realistic understanding of non-western parts of the world (David Cameron makes shock comeback in high-risk reshuffle, 13 November).
Had Mr Cameron been a skilled negotiator, it is highly probable that he would have won sufficient concessions from the EU, in particular on control of our borders, to achieve a remain vote in the 2016 Brexit referendum. Because he would not call Angela Merkel’s bluff and was incapable of threatening to lead the leave campaign, he came home empty-handed.
