[6] On 3 February 1999, Westminster joined the Atlantic Patrol Ship South, relieving HMS Norfolk which was taking part in Operation Basilica in Sierra Leone.200 naval officers and sailors in full ceremonial uniform paraded through the streets of London from Westminster Abbey to Horse Guards as part of the celebration service.The honour entitles the crew the freedom to "parade through the City on all ceremonial occasions in full panoply and with drums beating, colours flying and bayonets fixed".[9] The frigate was deployed to Burma in May 2008 to spearhead the British relief effort after Cyclone Nargis devastated the country, but later had to withdraw after the junta refused to grant permission for aid to be landed.[13] Whilst in the Persian Gulf she made a port call in Dubai where one of her sailors (Leading Seaman Timothy Andrew MacColl, 27, from Gosport in Hampshire)[14][15] disappeared, prompting a bilateral search between the Royal Navy and local authorities.In September 2013, she practised anti-submarine drills with the Italian Navy's Sauro-class submarine Salvatore Pelosi and the Durand de la Penne-class destroyer Francesco Mimbelli.
