The Queen and the Duke of Edinburgh are to give their royal seal of approval to a Sussex town's revamp.

Her Majesty and Prince Philip will visit Horsham on October 24 when they will tour the newly renovated town centre.

They will then unveil a sundial plaque to mark the official opening of the new public space following a 25-year renovation project.

The royal couple will also go to Christ's Hospital school, off Tower Hill, where they will be joined by the Duke and Duchess of Gloucester.

The boarding school is celebrating 450 years since Edward VI granted its Royal Charter in recognition of its charitable work.

The Queen will meet pupils, staff and parents before unveiling a commemoration stone in the dining hall before 300 guests.

She will then continue to Horsham town centre where she will inspect the new facilities, including the Capitol arts centre.

Councillor Liz Kitchen, leader of Horsham District Council, said: "We are all thrilled the Queen and the Duke of Edinburgh are coming to visit Horsham.

"For the people of this district, this is the highest accolade and it marks the culmination of a 25-year vision for the redevelopment of Horsham."

Dr Peter Southern, headteacher of Christ's Hospital, said: "It is a great honour for Christ's Hospital to receive the Queen and the Duke of Edinburgh and the Duke and Duchess of Gloucester.

"The pupils, staff and trustees are looking forward to welcoming them and providing a glimpse of the very special opportunities given to children from all walks of life at Christ's Hospital."

Tom O'Hara, chairman of North Horsham Parish Council and former Mid Sussex district councillor, was presented to the Queen when she opened The Triangle leisure centre in Burgess Hill.

He said of the forthcoming visit: "Based on my own experience in Burgess Hill, I think the support given and the mere fact you have the Queen of the realm in attendance is a huge boost to everyone's morale and confidence."
