The Duchess of Sussex has pulled out of making a joint speech with the Duke of Sussex in Brussels about online child safety because she is "not strong enough" after her father's arrest.

Harry and Meghan had both been due to deliver the keynote address to the European Parliament on Tuesday.

The duchess will still join Harry at the event, but has decided not to speak after Thomas Markle Sr appeared in court on Friday charged with possession of child abuse material.
