Largest cruise ship built for UK is named in Southampton
Take That star Gary Barlow performed at the ceremony
The largest cruise ship built for the UK market have been officially named in Southampton.
P&O Cruises' Iona has 17 passenger decks, creating capacity for 5,200 holidaymakers before social distancing is taken into account.
She will be used by the operator for its summer season of domestic sailings.
The vessel is the first British liner fuelled by liquefied natural gas, which the operator described as "one of the cleanest fuels in the world''.
Ships of her size are normally powered by diesel engines which emit nitrogen oxides, affecting air quality.
Iona - 345 metres long (1,132ft) and weighing 185,000 tonnes - was built at the Meyer Werft shipyard in Papenburg, Germany.
She will sail on her maiden cruise to the Scottish island she was named after on August 7.
Sunday night's naming ceremony featured a performance by Take That star Gary Barlow, who is music director of an onboard entertainment venue.
The coronavirus pandemic meant the event was closed to the public but was broadcast online to a virtual audience of 25,000 people.
Dame Irene Hays, owner of travel agent Hays Travel, is the ship's godmother and conducted proceedings.
The first major sailing following Monday's lifting of the ban on cruises in England will be operated by MSC Cruises.
Its ship Virtuosa will set off from Southampton for a four-night trip beginning on Thursday.
Cruises operating in England will only be allowed to carry up to 1,000 passengers - or 50% of their capacity if that is lower - until all limits on social contact are removed.
Under Boris Johnson's road map for easing restrictions, that was due to take place on June 21 at the earliest, but the Prime Minister has warned that the Indian coronavirus variant means his plan is in jeopardy.
