It has come to light that the Princess of Wales accompanied Prince William for an engagement on Wednesday.

This week, the Princess of Wales quietly undertook her initial royal engagement, just days after withdrawing from Royal Ascot previously. The Court Circular reports that on Wednesday, the Princess and Prince William appeared together in Windsor.

The American philanthropist Melinda French Gates was welcomed by the royal couple at Windsor Castle. Ms. French Gates, the ex-wife of Microsoft creator Bill Gates, is an entrepreneur herself as she established Pivotal Ventures, a firm focused on enhancing women’s strength and impact.

She is additionally the co-founder and previous co-chair of the Gates Foundation.

William and Kate conducted a discreet meeting, which was held without any photos being shared, in their capacity as patrons of their Royal Foundation.
