Prince Harry has spoken out about the upcoming royal wedding during a training exercise for his North Pole trip, revealing he and other members of the royal family thought William and Kate would never make it down the aisle.

THE ROYAL WEDDING: ALL THE DETAILS

Speaking of the impending April 29 wedding, the 26-year-old – who is currently preparing for a grueling Artic trek, to raise money for charity Walking With the Wounded – admitted he thought a wedding was 'never going to happen' for his older brother.

Harry also told of how his thoughts have turned to his mother, Princess Diana, and how he will remember her during the special ceremony.

'Myself, my brother and my father, there will be all sorts of people and the rest of the family that will be no doubt be thinking about it,’ he said. 'And I hope she would be very, very proud that the big day has come upon him.

'We all thought that it was never going to happen for him. But it has happened, and I think everyone's going to be very proud of him.’

The cheeky prince also opened up on his best man duties, joking that he’ll be keeping his speech clean and simple – as the Queen will be in earshot.

'I'm doing the speech along with a couple of his friends, so I will take the mickey out of him.

'I will tell a few stories, but I think my grandmother will be there, so I'll have to be selective.

‘The speech will be like any normal best man's speech,’ he added. ‘Between the three of us we will make sure people know the good times and the bad times that he's had since he was a nipper.’

Finally, Harry spoke of how he was looking forward to welcoming ‘fantastic’ Kate Middleton into the family.

'A younger brother or younger sister would have been nicer, but to have a big sister is obviously very, very nice,’ he said.

'I've got to know Kate pretty well, but now that she's becoming part of the family, I'm really looking forward to getting her under my wing - or she'll be taking me under her wing probably.

'She's a fantastic girl. She really is. My brother's very lucky, and she's very lucky to have my brother. I think the two of them are a perfect match.'
