Kate Middleton’s kisses for Roger Federer 'broke royal protocol'

Kate Middleton famously planted three royal kisses on tennis ace Roger Federer

when he won a Wimbledon title in 2017, and according to Express UK,

the Duchess of Cambridge effectively broke royal protocol with the gesture.

Wimbledon 2022 returned to full capacity in three years after the COVID-19

pandemic, and while Federer was notably missing from the tennis event,

royal fans took the moment to reminisce on his 2017 win against Marin Cilic.

The moment instantly went viral at the time after Kate Middleton,

who is understood to be good friends with the Grand Slam legend,

not only cheered Federer on, but also gave him three demure kisses after his win.
