Prince Harry and Meghan Markle could hold a public ballot to invite people to their wedding.
The couple confirmed on Monday (27.11.17) they were engaged to be married and on Tuesday (28.11.17) it was revealed they will tie the knot at Windsor Castle in May 2018, and they are said to be keen to ensure the British public feel "part of the celebrations".
According to the Daily Telegraph newspaper, the pair are "working through ideas for how this might be achieved".
One potential way of doing this would be to follow in the footsteps of Harry's uncle Prince Edward's wedding to Sophie Rhys-Jones in 1999 when they had a ballot for 8,000 people to be a part of the nuptials inside the castle.
They also took a carriage ride through the town of Windsor, where 30,000 people lined the streets to see them on their big day.
Earlier this week, Kensington Palace communications secretary Jason Knauf admitted Harry and Meghan were pleased that so many people in the UK and around the world were celebrating their engagement news with them, and admitted the couple are keen to get the public involved in their big day.
He said: "Prince Harry and Meghan Markle are extremely grateful for the warm public response following yesterday's announcement of their engagement.
"In a happy moment in their lives, it means a great deal to them that so many people throughout the UK, the Commonwealth, and around the world are celebrating with them.
"Prince Harry and Ms. Markle are delighted that the beautiful grounds of Windsor Castle will be where they begin their lives together as a married couple.
"The couple of course want the day to be a special, celebratory moment for their friends and family.
"They also want the day to be shaped so as to allow members of the public to feel part of the celebrations too and are currently working through ideas for how this might be achieved."
Harry, 33, and Meghan, 36, have been dating for around 16 months after being introduced by a mutual friend.
