Former top UK official believes intensifying economic pressure on Tehran would erode internal support for regime

The UK should back Donald Trump’s expected maximum economic sanctions against Iran as part of an effort to encourage nationals to end their support for the current regime in Tehran, Mark Sedwill, the former cabinet secretary, argues in a report published on Monday.

He writes: “It is not for the west, let alone the UK, to determine who rules Iran. That is for the Iranian people. But we can make clear that the right choice will bring benefits just as the wrong one will bring more of the same.”
