The Princess of Wales has penned a heartfelt letter to the Irish Guards, expressing her well wishes for their upcoming Colonel's Review in London on Saturday. As the regiment's Colonel, Kate conveyed her regret at missing the event, which serves as the final rehearsal for the Trooping the Colour parade.

In her letter, the Princess wrote, "I wanted to write and let you know how proud I am of the entire regiment ahead of the Colonel’s Review and Trooping the Colour." She acknowledged the dedication and hard work invested by the troops, stating, "I appreciate everyone trooping this year has been practising for months and dedicating many hours to ensuring their uniforms and drill are immaculate."

Kate further expressed her deep honor in serving as their Colonel, adding, "Being your Colonel remains a great honour and I am very sorry that I’m unable to take the salute at this year’s Colonel’s Review." She extended her apologies to the entire regiment, assuring them, "Please pass my apologies to the whole regiment, however, I do hope that I am able to represent you all once again very soon."

The Princess is currently recovering at home following treatment for cancer.
