Resurrected Former PM has experience, but appointment is not without risk

There is a danger that Lord Cameron, with six years' experience as prime minister and umpteen world summits under his belt, as opposed to Rishi Sunak's single year, will be tempted not just to dominate foreign policy but to stray out of his lane and give very broad advice to his boss.

But with only a year to go till the next election and two of the biggest foreign policy crises to face the UK since the Iraq war, Sunak will hope that Cameron's major contribution will be to bring an air of stability and authority to the UK's foreign policy.

The perception overseas has been that Britain has been a country at best suffering strategic drift and at worst on the verge of a nervous political breakdown. Only the contribution in Ukraine - playing to British security and defence strengths and the UK's intangible soft power have prevented decline turning into something worse.
