On Wednesday 9th May, the day after President Trump’s announcement of his controversial decision to withdraw the US from the Iran nuclear deal, we were delighted to have the opportunity to welcome to GSF Sir Simon Gass KCMG CVO, Political Director at the Foreign and Commonwealth Office (2012-2016). Recognised as the British Government’s most senior expert on Iran – he was British Ambassador to Tehran (2009-11), he led the UK team at the prolonged E3+3 negotiations which resulted in the Iran Nuclear Agreement in July 2015 and he was the architect of the restoration of full diplomatic relations between the UK and Iran in 2016, Sir Simon gave a lecture entitled ‘Iran And The West: Deal Or No Deal?’ in an event which was chaired by Lord Lothian.
