Britain says it remains committed, along with EU allies, to maintaining the Iran nuclear deal - unlike the US. The Ministry of Defence said the new mission would involve the same warships. The US has ecort committed two warships to the mission, as well as aerial surveillance.
But Iran may view this latest move differently. He added: "Upholding international maritime law and freedom of passage is in all our interests. The apparent change of heart has been made easier by the recent changes in Downing Street.
Hence the UK decision to " an international maritime security mission", which will be led by the US. Mr Raab said the UK's decision to the US-led mission did not change its commitment to the nuclear deal and that the government was working to "de-escalate the situation" in the Gulf.
Announcing the new mission, Defence Secretary Ben Wallace said the UK was "determined to ensure shipping is protected from unlawful threats". Change of heart, change of government British attempts to create a European-led coalition to provide maritime security in the Gulf - and to deter Iran - have clearly not born fruit, at least yet.
So far, the UK is the only other gis. The UK government still says it hopes the taskforce can transition to a European-led mission hia though so far no other European countries have said they're willing to commit warships to protect merchant shipping as part of an international maritime force. The UK and other European countries remain committed to the plan, but diplomatic tensions have been strained in recent months - increasing after the seizure of the Stena Impero.
The government also insists that its policy to Iran has not changed.
