The Queen has made sport the central focus of her Christmas message this year, Buckingham Palace has revealed.

白金汉宫透露，女王将运动作为她今年圣诞致辞的中心焦点。

She emphasises how it can be used to build communities and create harmony, and highlights the important role that volunteers play.

Her message will also focus on how sport can be used to encourage the development of vital social skills.

The address will be broadcast in full on radio and television at 1500 GMT on 25 December.

The Queen will say: "In the parks of towns and cities, and on village greens up and down the country, countless¹ thousands of people every week give up their time to participate in sport and exercise of all sorts, or simply encourage others to do so.

"These kinds of activity are common throughout the world and play a part in providing a different perspective on life."

Footage showing William and Harry² and a group of young African orphans³ from Lesotho bonding as they play football is included in the broadcast.

The Princes visited the country in June and travelled to the remote Semongkong Children's Centre to meet the youngsters, during a tour of southern Africa.

Christmas Day messages are normally recorded at Buckingham Palace, but this year the Queen suggested Hampton Court Palace - the first time it has been used.

The broadcast, produced by ITN, will be available on the Royal Channel of the YouTube website.

It will also be shown in Commonwealth⁴ countries and on the British Forces Broadcasting Service.
