Why has Kate decided to attend Trooping the Colour?
Sources have suggested that as the Princess herself said in her message, she enjoys spending personal time on the things that give her energy and positivity and connecting with nature is something that continue to support her recovery.
It is thought that the Princess chose to dip back into the public spotlight for her first public appearance at Trooping because family is so important to her and she wanted to be there to support husband and children.
Her return to work is considered one of the first steps to regaining her strength.

What events in the future could Kate attend?
While her attendance at Trooping the Colour will undoubtedly be a 'significant moment', it has been strongly stressed that it should not be seen as a return to a full schedule of public engagements.
As Kensington Palace said in March, the Princess may be keen to attend events over the course of the summer, as and when she feels able to, with the support and guidance of her medical team.
Any future engagements will be announced closer to the time, although the Mail understands that Kate will not be present at Monday's Order of the Garter ceremony or Royal Ascot next week.
However it is understood that the Princess is feeling well enough to start working from home a little and has been holding meetings at Windsor.

What will tomorrow's Trooping the Colour look like?
With Kate's bombshell announcement that she will be attending tomorrow's Trooping the Colour, we can now give a few more details about what will happen.
- The Princess will travel with Prince George, Princess Charlotte and Prince Louis in a state carriage down the Mall and watch the parade from the Major General's Office with the rest of the royal family.
- It is also hoped that she will later appear on the balcony of Buckingham Palace with the rest of the family, although she may have to see how she feels on the day and plans may yet be amended.
- The Princess is and remains the Colonel of the Irish Guards but under the circumstances, Lieutenant General James Bucknall is taking the salute on her behalf.
- Prince William will be on horseback during the parade as he has been in previous years.
- The parade will be broadcast live on the BBC from 10.30am until 1.10pm.

'I have been blown away by all the kind messages of support and encouragement over the last couple of months.
'It really has made the world of difference to William and me and has helped us both through some of the harder times.
'I am making good progress, but as anyone going through chemotherapy will know, there are good days and bad days.
'On those bad days you feel weak, tired and you have to give in to your body resting. But on the good days, when you feel stronger, you want to make the most of feeling well.
'My treatment is ongoing and will be for a few more months. On the days I feel well enough, it is a joy to engage with school life, spend personal time on the things that give me energy and positivity, as well as starting to do a little work from home.
'I’m looking forward to attending The King’s Birthday Parade this weekend with my family and hope to join a few public engagements over the summer, but equally knowing I am not out of the woods yet.
'I am learning how to be patient, especially with uncertainty. Taking each day as it comes, listening to my body, and allowing myself to take this much needed time to heal.
'Thank you so much for your continued understanding, and to all of you who have so bravely shared your stories with me.'
