The Princess of Wales’ parents looked to be in high spirits on the fourth day of Wimbledon – in their second public appearance since their daughter’s cancer diagnosis.

Carole and Michael Middleton were all smiles as they enjoyed watching the action from the Royal Box on Thursday.

The couple also appeared very focused as they took in the second round match between Serbia’s Novak Djokovic and Britain’s Jacob Fearnley.

Both also laughed as they chatted with other attendees, including Sebastian Coe, the President of the International Association of Athletics Federations.

Dressed in all their finery, the beaming couple looked in good spirits as they arrived side-by-side for the prestigious event in London.

The pair also brought shades for the sunny day – with Carole sporting trendy retro style glasses.

It follows their cheerful appearance at Royal Ascot last month, when they joined members of the Royal Family, including their son-in-law Prince William, at the lavish occasion.

The Middletons’ outings come after their daughter Kate, 42, who has been receiving chemotherapy for an undisclosed form of cancer since February, made a spectacular return to public life during Trooping the Colour last month.

Carole has reportedly been supporting her daughter through her cancer treatment at her home in Windsor.

Michael and Carole’s last public appearance before Royal Ascot was at Kate’s annual Royal Carols: Together at Christmas at Westminster Abbey in London in December. Three months later, Kate announced to the world her cancer diagnosis.

But the royal’s parents have returned to the spotlight recently for the summer social scene after spending months at their daughter’s side.
