Business leaders are urging the Government to capitalise on the global media coverage of the Queen's Diamond Jubilee celebrations.
Her Majesty will continue to mark her 60 years on the throne today after four days
of public celebrations which she has described as a "humbling experience" .
She will sit down at a lunch laid on in honour of the anniversary with Commonwealth leaders, including prime ministers, governor generals and high commission representatives.
The Duke of Edinburgh had been due to accompany the Queen to the event at Marlborough House on Pall Mall in London, but he remains in hospital under observation for a bladder infection.
Millions of people both at home and abroad have been lapping up the wall-to-wall television, radio, newspaper and online offerings thrown up by the festivities - and the Institute of Directors (IoD) is among those pushing for a legacy dividend from the Jubilee .
Mark Wallace from the IoD told Sky News: "Everybody knows how crucial exports are going to be to the future of this country when everyone around the world is fighting for space.
"We have had top billing for four days around the world and now we've got to make sure everything from tax rates to the welcome you get at UK airports says 'hello we're Britain come and invest in us.'"
The four-day Jubilee weekend has boosted UK tourism spending by an estimated £700m .
Four million people are said to have taken overnight trips in the country to mark the occasion, according to Visit England.
While the effect of the extra bank holiday on the economy is estimated to be a loss of £1.2bn, it is hoped the pageantry and pride showcased across the world will more than make up for it in the long term.
The monarchy too appears to have reaped a warm reward from the nation.
Royal Historian Dr Tracy Borman said: "It's extraordinarily significant, it has re-established the popularity and place of monarchy in British society."
Dr Borman believes that alongside the Queen, her heir, the Prince of Wales has boosted his capital with his future subjects.
"I think the real rank outsider and surprise winner would be Prince Charles. His image has improved enormously this weekend," she said.
Will the post-jubilee glow have tangible results for the country and its balance sheet? It is too early to know.
But it is clear the marking of the Queen's 60 years on the throne has been much more than just a monumental knees-up.
