The couple recently celebrated their daughter Mia's first birthday but are not thinking of expanding their family further yet because the 33-year-old eventing champion is focusing on competing in the 2016 Olympics in Brazil.

Mike said: "We've got an Olympics in Rio to deal with first."

Though the couple live in a house on Zara's mother Princess Anne's Gatcombe Park estate in Gloucestershire, South West England, the 36-year-old sportsman insisted they don't benefit from their royal connections.

He said: "They don't give us any money.

"We look after ourselves - we don't get anything for free."

And Mike - who is preparing to compete on Channel 4 celebrity contest 'The Jump' - insisted he doesn't have to ask royal permission before doing anything in public, but will consider the impact it would have on their household.

When asked if he considers how things might reflect on them, he told Radio Times magazine: "That would always come up, yes, of course, but ultimately it's what we want to do first."

In 2011, Mike was fined £25,000, reduced to £15,000 on appeal because of a drunken night out during the Rugby Word Cup in New Zealand but insists he has no regrets over his behaviour, which included throwing a dwarf.

Asked if he regrets his actions, he said: "No, not really.

"It's easy to look back and say you wish it hadn't happened.

"If you'd asked me, do I regret going out and having a good time with the fans and all the boys? No.

"But obviously if I had known the spin-off from it all, I wouldn't want that.

"Quite a big mountain was made out of a fairly small molehill."
