The agency emphasized that the events that took place in the region over the past four months, including the capture of a tanker under the British flag Stena Impero, indicate a growing threat to commercial shipping.
"The Royal Navy will work with the US Navy to ensure the safety of merchant ships in the Strait of Hormuz," the British ministry said in a statement.
Defense Minister Ben Wallace, in turn, announced the country's readiness to defend its courts against “unlawful encroachments”.
At the same time, Great Britain also emphasized the invariability of their position with respect to Iran in the matter of preserving the nuclear deal.
“We remain committed to working with Iran and our international partners to de-escalate the situation and preserve the nuclear deal,” the statement from the British Foreign Minister, Dominic Raab, quoted the military department as saying.
Earlier in Germany, they announced their refusal to participate in the US coalition in the Strait of Hormuz.
On July 26, US Secretary of State Mike Pompeo said that Washington had sent requests to Britain, France, Germany, Norway, Japan, South Korea, and Australia with a proposal to join the security coalition in the Strait of Hormuz.
On July 19, Iran detained the Stena Impero tanker under the flag of Great Britain "in connection with its violation of international shipping rules" in the Strait of Hormuz.
