Meghan Markle broke an age-old royal rule during her wedding to Prince Harry, according to a bombshell new book.

The Duke and Duchess of Sussex have become well known for departing from royal traditions.

And it seems Meghan, a former actress, stepped away from Royal Family usual protocols as she tied the knot with Harry.

After much speculation, it has been reported that the bride gave her own toast on her special day.

At the time of the wedding there were rumours that the divorced American had done so – but it appears to have been confirmed in Finding Freedom, a new biography claiming to give an insight into the young royal’s life.

Written by veteran authors Omid Scobie and Carolyn Durand, the pair claim Meghan broke the royal rules and gave a speech at the reception.
