Daniel Bruce: Why the new Dfid and Foreign Office team must lead the way in tackling aid corruption

Bob Seely: How Iran is seeking to hit the West where it hurts – at the petrol pumps

Benedict Rogers: Hunt has made a strong start in placing values at the heart of British foreign policy

From Hong Kong to Yemen to Burma the Foreign Secretary is making positive steps. There is still more to do, however.

Garvan Walshe: Why Khashoggi’s murder is Erdogan’s chance to strike

The killing gives Turkey’s autocrat the opportunity to make common cause with the Saudi prince’s enemies.
