Prince Harry and David Cameron in New York to promote UK
Prince Harry has met UK Prime Minister David Cameron in New York to encourage more Americans to visit, study and do business in Britain.
They visited the city's Milk Studios after arriving on a red double-decker London bus.
Earlier, Mr Cameron visited the site of last month's Boston marathon bombings, in which three people were killed and more than 260 were injured.
Meanwhile, Prince Harry met survivors of October's Superstorm Sandy.
The pair are on separate visits to the US.'Great' campaign
A new version of London's red Routemaster, a New Bus for London, carried the two men to Manhattan's Meatpacking District for an event highlighting creative UK firms in the US.
The event is part of the Great campaign, a government initiative which promotes the UK around the world as a place to visit, study and do business in, following the success of the Diamond Jubilee and London 2012.
Thomas Heatherwick, who created the cauldron in which the Olympic flame burned for the duration of the London Games, helped design the new bus, commissioned by London Mayor Boris Johnson.
He joined about 100 guests, who included British actress Emilia Clarke, who stars in US fantasy series Game of Thrones, and senior executives from companies such as Virgin and British Airways at the reception, held in a fashion photographic studio that has been used by Madonna.
The prime minister and the prince were presented with dolls of themselves created by UK firm Makies. They were also shown 3D-printing technology and innovative crafts kit.
Addressing the audience, Mr Cameron said Britain and the US had "brains, brilliance and creativity" and needed to "play to our strengths".'Devastating'
Prince Harry spent the morning visiting New Jersey communities hit by Superstorm Sandy.
The storm struck the US east coast in October, killing more than 120 people. The cost of the clear-up is set to run into tens of billion of dollars.
The prince had asked to see how people were rebuilding their lives after he met a US soldier during his deployment to Afghanistan last year who had lost his home in the natural disaster.
With New Jersey's governor Chris Christie as his tour guide, the prince flew in by helicopter to visit the seaside towns of Mantoloking and Seaside Heights.
Asked by Maria Hunter, who helped with the relief efforts, what he thought of the scenes in Mantoloking, the prince said: "It was devastating."
Later, he is scheduled to throw a pitch to promote a community baseball programme involved with a royal foundation.
Prince Harry began his seven-day trip of the US by meeting Michelle Obama and joining her in honouring America's military mothers at a White House reception.
He also visited an exhibition highlighting the work of a landmine charity supported by his mother, Princess Diana.'Stand with you'
Mr Cameron paid tribute to the spirit of Boston's people as he visited the site of the marathon bombing.
He toured the memorials in Copley Square accompanied by Massachusetts Governor Deval Patrick.
"Everyone in the UK stands with your great city and your great people," he told reporters in the square.
Mr Cameron is on a three-day trip to the US.
On Monday, he held talks with President Barack Obama on issues including Syria, Iran and global trade.
