Duke of Cambridge, Prince William has unveiled a piece of art commemorating 800 years since the Magna Carta was signed.
The 32-year-old prince was met by artist, Hew Locke to view The Jurors, a sculpture which represents the 12 seats of the jury and is inspired by clause 39 of the historic document - which first protected the rights and freedoms of society and established that the king was subject to the law - and listened to speeches from 11 actors before joining them in the 12th chair, then unveiling a commemorative plaque.
The Queen Elizabeth did not give a speech at the event, but she did unveil a plaque at the service which was held where King John signed the document in 1215 and wrote in the programme that the Magna Carta's principles were "significant and enduring".
Attorney General Philip Hammond MP said, "For those who drafted the US constitution, the significance of Magna Carta was clear.
"We are working with partners in the US and around the world to pursue nations who deny human dignity."
Also during the celebration, Prime Minister David Cameron and Lord Dyson, the Master of the Rolls, gave speeches, and the Red Arrows soared over the meadow at 12.15pm.
