Sir Oliver has raised his concerns in Parliament about the Iran deal meaning more money to the IRGC, and about the loud music disrupting statements from Downing Street.

Sir Oliver asked: "Does the Deputy Prime Minister share my concern, and that of many of my constituents, about elements of the Iran deal, in particular that the early sanctions relief, access to frozen Iranian assets and $300 billion of economic reconstruction development aid could find its way back to the Islamic Revolutionary Guard Corps, further strengthening an organisation that has done so much damage to regional stability and global stability, both directly and through its proxies?

While I am at it, will the Deputy Prime Minister sit down with the police and find some way of stopping the ridiculous heckling and disruption of Prime Ministers on the steps of Downing Street when they are trying to make statements, which further adds to our considerable international embarrassment right now?"

The Deputy Prime Minister responded: "I am very grateful to the right hon. Gentleman for his question. We have sanctioned the entirety of the IRGC. Since coming into office, we have imposed 240 sanctions on Iran, and we will bring forward legislation to implement full and further sanctions and sectorial measures, including targeting finance, energy, software and other industries that are advancing Iranian nuclear escalation.

The right hon. Gentleman has stood in my shoes on the steps of Downing Street. There are moments where the country is watching, and people want to be able to hear Prime Ministers of the day speak, so I recognise his point."
