Prince Harry Supports Cause in London While Prince William Is in Wales

Prince Harry is back in London during his U.K. trip to visit Imperial College London’s Centre for Blast Injury Studies.

On Sept. 10, the Duke of Sussex got an update on the work of the Centre for Injury Studies and its more recent focus on paediatric blast and crush injuries. Following a laboratory tour, he participated in a roundtable discussion on efforts focused on mental health and medical evacuation in conflict.

Prince Harry, 40, opened the Centre for Blast Injury Studies’ new laboratories in 2013 and also attended part of the Blast Injury Conference in 2019.

The Duke of Sussex arrived back in the U.K. on Sept. 8. After traveling to Windsor Castle to visit the burial site of his grandmother Queen Elizabeth on her death anniversary, Harry attended the WellChild Awards in London that evening. The following day, he traveled to Nottingham to meet social action groups and local charities.

A source told PEOPLE that Harry arrived in the U.K. in a “positive” mood. “He’s in a really good headspace and looking forward to seeing everyone from his charities and the causes he cares about,” the source said.
