According to a spokesman of the UK Prime Minister Theresa May, the British head of government will meet with Gibraltar's Chief Minister Fabian Picardo to discuss the detained Iranian supertanker and Brexit issues.
Earlier this month, London said it would send several Royal Navy ships to the Persian Gulf, claiming that Iranian forces had tried to seize British oil tankers travelling through the waterway in response to the detention of Grace 1. Tehran has denied the claims but stressed that Britain had endangered the safety of navigation by its actions in Gibraltar.
The row comes amid an escalation of tensions between Washington and Tehran, as the US has deployed additional troops near Iran's borders and ramped sanctions against the country.
In the meantime, the Islamic Republic has suspended some of its obligations under the 2015 nuclear deal and started enriching uranium since the US left the agreement, as European countries have been unable to shield Tehran from the unilateral restrictions imposed by Washington.
