A first for the Duchess of Cambridge
: She has been officially named a patron of the foundation set up by Prince William
and Prince Harry.
This marks a first royal patronage for Kate, 29, and a likely name change for the Foundation of Prince William and Prince Harry
. Trustees are "considering changing the name," according to a palace source.
The move from a supporting role to an official one was something of a formality, with Kate joining the princes in utilizing the foundation "as their main charitable vehicle but in the way that it will be grant-giving rather than anything else," the source says.
Only last week, after Kate's visit alongside William, 29, to open a a children's cancer unit
at the Royal Marsden Hospital, she joined the princes at a special reception back at St. James's Palace.
There, the trio thanked those who had helped the grant-giving body through the year and met some potential new donors to the cause.
And it was at the party that her formal involvement was announced. The decision had been made earlier in the day by the trustees.
