They are only four sentences, but they have triggered further speculation that something significant is about to happen in the life of Prince Harry’s girlfriend Meghan Markle.

In a brief statement posted online the American actress has announced that she is to discontinue her online blog The Tig.

Markle, who has been dating the Prince for nearly a year and has been increasingly photographed with him in London and elsewhere, said it was time to “say goodbye” to the blog after three years.

She writes: “What began as a passion project (my little engine that could) evolved into an amazing community of inspiration, support, fun and frivolity. You've made my days brighter and filled this experience with so much joy.”

Markle adds: “Keep finding those Tig moments of discovery, keep laughing and taking risks, and keep being "the change you wish to see in the world."

“Above all, don't ever forget your worth - as I've told you time and time again: you, my sweet friend, you are enough.”

The 35-year-old reproduced the announcement on her Instagram page, and in the space of just 15 hours it had attracted more than 11,000 ‘likes’ from her followers.
