The Britain’s Ministry of Defence also affirmed the participation of the HMS Montrose frigate to "ensure the continuous availability of ships to accompany merchant vessels".

This UK’s deployment is the process of carrying out the mission to escort the British – flagged ships went through the strategic area, Strait of Hormuz as it had announced last week.

Defence Secretery, Ben Wallace shared that "Freedom of navigation in the Strait of Hormuz is vital not just to the UK, but also our international partners and allies.

He expressed "Merchant ships must be free to travel lawfully and trade safely, anywhere in the world. I'm pleased that HMS Duncan will continue HMS Montrose's fine work in helping to secure this essential route” and added "While we continue to push for a diplomatic resolution that will make this possible again without military accompaniment, the Royal Navy will continue to provide a safeguard for UK vessels until this is the reality."

The Iran – UK confrontation continue rising after the Iran’s seizure of British oil tanker, Stena Impero which the UK suspected it was the Iran’s revenge for the capture of Iranian oil tanker Grace 1 in Gibraltar. Particularly, Iranian President Hassan Rouhani announced Iran will set Stena Impero free when the UK released Grace 1 on Wednesday

Moreover, at the meeting on saving the 2015 nuclear deal on July 28, Iran also said the UK’s capture of Iran’s oil tanker was the breach of the deal.
