Prince Harry and Meghan Markle wedding could cost more than $30 million

It will be a wedding fit for a prince, with a price tag that could make King Midas blush.

Prince Harry and Megan Markle’s announcement that they will marry next spring sent London into a tizzy Monday morning that may last through the marriage ceremony.

The British capital knows what a “wedding of the century” entails after being strung along through the fanfare of Harry’s older brother William tying the knot six years ago, though the red-haired royal and his Canadian bride-to-be could eclipse the staggering figures spent in 2011.

Reports estimated the security cost at around 20 million pounds, or upwards of $32 million given exchange rates at the time, with the majority of the money going to extra police and their overtime.

Costs for the wedding itself were paid for by the Royal Family, with an additional undisclosed sum from the family of bride Kate Middleton.

The ruling clan, the Mountbatten-Windsors, will likely want to avoid attracting criticism with any particularly extravagant displays, though security costs for the wedding next year could also balloon given recent concerns about terrorism.

Armed police have been a more regular presence on the streets on London since a string of deadly attacks in Manchester, outside Parliament and at the city’s Borough Market earlier this year.

It is unclear whether an increased bill for security will move the younger prince and Markle's wedding past the estimated 30 million pounds spent by his parents Prince Charles and Princess Diana in 1981.

The upcoming wedding is also expected to be a public holiday in the United Kingdom, where the Center for Economics and Business Research said in 2012 that the cost of each such day off was 2.3 billion pounds in lost productivity.

Questions about the cost of another royal-themed party also come as matriarch Queen Elizabeth II has recently come under scrutiny for investing millions in offshore tax havens.

Elizabeth is expected to receive more than 80 million pounds from the British treasury for a fiscal year starting 2018, part of what anti-monarchy group Republic estimates as a 345 million pound cost for the monarchy as a whole.
