The reopening of the British embassy in Tehran is a startling development which represents a potential turnaround in our history with Iran.
The Foreign Secretary is today expected to announce plans to strengthen diplomatic ties with Iran.

An Iranian mathematician has become the first female recipient of the Fields Medal - the highest recognition in the discipline.
Maryam Mirzakhani, a professor at Stanford University in California, won the prize for her work on “the dynamics and geometry of Riemann surfaces and their moduli spaces.”
Mirzakhani was born in the Iranian capital Tehran and won gold medals in the International Math Olympiad twice as a teenager, before moving to the US for her doctorate.
Her former tutor, Curtis McCullen, praised her "fluency in many disciplines, which is unusual in the modern era, when considerable specialization is often required".
The Fields Medal, awarded by the International Mathematical Union since 1936, is sometimes referred to as the "Nobel Prize of Mathematics".
All of the 40 passengers including seven children aboard a plane that crashed in the Iranian capital Tehran have died, according to the country's official news agency IRNA.

The source, who spoke on condition of anonymity, said: "I can tell you that Kerry will be in Vienna this weekend, probably on Saturday."
However, the official added it was unlikely there would be an agreement signed in the near future, given the disagreements between Iran and western nations over Tehran's nuclear programme.
The UK Foreign Secretary William Hague rejected a claim the government was "softening" its approach to Iran.
Speaking in the parliament, Mr Hague described the UK as "absolutely relentless" in its efforts to defeat terrorism around the world and added: "I can assure you that there is no softening of any of our policies in relation to Iran.
William Hague might have announced the reopening of the British embassy in Tehran today, but the Foreign Office is still advising people against traveling to the Middle Eastern country.
The Foreign Office currently advises "against all but essential travel" to most of the country, and "against all travel" to the eastern parts of Iran near the borders with Afghanistan and Pakistan.
People planning to travel to Iran should check the Foreign Office travel advice regularly and sign up for email alerts on the security situation, the spokesperson said.
The Secretary of State William Hague has issued a statement on the possible reopening of the British embassy in the Iranian capital, Tehran:
– William Hague
Our two primary concerns when considering whether to reopen our embassy in Tehran have been assurance that our staff would be safe and secure, and confidence that they would be able to carry out their functions without hindrance.
There are a range of practical issues that we will need to resolve first.
However it is our intention to reopen the Embassy in Tehran with a small initial presence as soon as these practical arrangements have been made.
