On May 19 this year US actress Meghan Markle and flame-haired Prince Harry will take a very important walk down the aisle of St George's Chapel, Windsor to exchange vows. Who will be lucky enough to attend this history-making wedding has been the topic of every water cooler conversation around the globe since the couple announced their engagement back in November last year.

Finally, Kensington Palace has released a number of details of who's on the list and who isn't. Earlier today Kensington Palace posted a tweet revealing 2,640 members of the UK public will be invited to join the celebrations in the Windsor Castle grounds. The Palace further shared that of those guests, 1,200 would be "young people who have shown strong leadership, and those who have served their communities."

The Palace shared the names and the stories of a number of the guests in the 1,200 strong list including: Philip Gillespie, Pamela Anomneze, Reuben Litherland and Amy Wright.

According to The Sun 600 guests have been invited to the wedding service at St George's Chapel with 200 of the couple's closest friends and family expected to attend the intimate evening reception at Frogmere House.

Who's on that list is unknown yet, but we do know who didn't make the list. In contrast to Prince William's 2011 wedding to Kate Middleton which included the who's who of political leaders, heads of state, royal relatives and celebrities including our very own Prime Minister at the time, Julia Gillard, The Guardian reports political leaders will not be invited to the wedding.

According to The Guardian a Kensington Palace spokesman said, "It has been decided that an official list of political leaders - both UK and international - is not required for Prince Harry and Ms Markle's wedding." Which means? No Donald Trump, no Malcolm Turnbull, no Theresa May and probably no Barack Obama either (unless he makes it in as a close friend of the couple, which is possible).

As for the celebrity contingent, the rumour mill has the Spice Girls reuniting for a special wedding performance as well as scoring seats at one of the highly sought-after reception tables. But we'll have to wait for confirmation from the Palace on this.
