The Queen has paid tribute to those who died in the First World War by laying a wreath of ceramic poppies at the Tower of London. She and Prince Philip visited the 'Blood Swept Lands and Seas of Red' evolving art installation in the former moat of the Tower.

To mark the the centenary of World War One, 888,246 poppies will be planted in the moat by a team of 8,000 volunteers, with the final poppy due to be planted on Armistice Day, 11 November. Each poppy represents a British or Commonwealth fatality in the First World War.

The installation was created by ceramicist Paul Cummins, who has been making the flowers since January with 40 helpers. Each poppy takes three days to make.

The poppies are for sale, with 10% plus all net proceeds going to six service charities.
