PRINCESS BEATRICE’S ROYAL WEDDING WON’T BE TELEVISED FOLLOWING PRINCE ANDREW’S EPSTEIN SCANDAL

People magazine previously reported that Beatrice and Mozzi will tie the knot on May 29 at a location that is yet to be announced.

The wedding will happen following Queen Elizabeth II’s palace garden parties, which traditionally are held in mid-May, and Beatrice and her sister, Princess Eugenie, are expected to attend at least one of the queen’s events.

The outlet reported on Wednesday that the royal reception is likely to take place at Buckingham Palace. Sources familiar with the plans also told the magazine that the ceremony itself should be near the palace and named a venue like the Royal Military Chapel, also known as the Guards Chapel, as a possible locale just across the road from Buckingham Palace.

It was also previously reported that British broadcasters BBC and ITV would not be broadcasting Beatrice’s big day like they did for her sister, Princess Eugenie, in 2018.
