Bookmakers are offering a plethora of Royal wedding betting opportunities for those wishing to take a punt on everything from the colour of the Queen’s hat to the song playing during Meghan Markle and Prince Harry’s first dance.

A large amount of money has been wagered on who will walk the bride-to-be down the aisle after her father, Thomas, said on Monday that he wouldn’t attend the event.

The current favourite to step in is her mother, Doria Ragland, who is odds on at 5/6 with PaddyPower. Meghan’s father has drifted out to 10/1, while Meghan walking the aisle solo is 6/1.

Donald Trump is at 2000/1 for anyone brave (or stupid) enough to take that bet. More likely, though still an outside chance, is Prince Charles at 16/1, while Prince Harry is 33/1 and Kate Middleton 100/1.

The Queen’s choice of hat has not been the focus of such attention since she wore blue and gold reminiscent of the EU flag during the state opening of parliament last year, causing some to speculate that the monarch was commenting on Brexit.

If the bookies’ odds are an accurate guide, the “Remain look” is apparently no longer in vogue in the royal household. Instead, money is going on the more traditional choices of purple (5/1) or green (4/6)

Keen royal fashion watchers will have noted that the form guide points to green, the colour favoured by Her Majesty at Royal Ascot in 2017 and the D-Day anniversary celebrations in 2014.

The newlywed prince and princess are likely to dance to a Whitney Houston number after the ceremony, according to Skybet. The American singer is the 2/5 favourite. Bob Marley is at a surprisingly short 10/1 while Elton John - who famously sang at the funeral of Princess Diana - is is at 2/1. Shaggy would be a genuine upset but is not to be ruled out at 66/1.

The question of who will attend appears to be a little more settled. Singer Sophie Ellis-Bextor is at 1/50, along with former Made in Chelsea star Millie Mackintosh and Elton John.

Gamblers can get ⅓ on golfer Rory McIlroy attending, 1/5 on David and Victoria Beckham and 4/6 on James Blunt.

Never shy of some publicity, Paddy Power are also offering “Any of the Kardashians” at a less-than-tempting 20/1 or Danny Dyer at 100/1.

If Robert Mugabe shows up, any lucky punters who backed the former Zimbabwean president will be toasting a shock 500/1 win.

The real winners, as ever, will be the bookmakers who are expecting to take hundreds of thousands of pounds in bets on the event.

Betfair spokesperson Katie Baylis said royal betting had been "through the roof" with thanks to the birth of Prince William and the Duchess of Cambridge's baby Louis and now the royal wedding.
