The Iranian Chargé in London is being informed now that we require the immediate closure of the Iranian Embassy in London and that all Iranian diplomatic staff must leave the United Kingdom within the next 48 hours.
If any country makes it impossible for us to operate on their soil they cannot expect to have a functioning Embassy here.
This does not amount to the severing of diplomatic relations in their entirety. It is action that reduces our relations with Iran to the lowest level consistent with the maintenance of diplomatic relations.
The House will understand that it remains desirable for British representatives to be in contact with Iranian representatives, for instance as part of any negotiations about their nuclear programme or to discuss human rights. But it does mean that both Embassies will be closed.
We wish to make absolutely clear to Iran and to any other nation that such action against our Embassies and such a flagrant breach of international responsibilities is totally unacceptable to the United Kingdom.
