London's mayor has called for a field of ceramic poppies to remain at the Tower of London beyond Armistice Day.
Boris Johnson said the popularity of the exhibition, in memory of Britain's war dead, meant he wanted to explore if it could be kept at the site for longer than originally planned.
The Royal British Legion has said it hopes the sale of the poppies will raise in excess of £15m.
The installation is currently scheduled to be dismantled on 12 November.
Entitled Blood Swept Lands And Seas Of Red, it is the work of ceramic artist Paul Cummins.
Up to four million people are expected to have visited before that date, when there will be 888,246 ceramic poppies, one for each British and colonial death during World War One.
Mr Johnson said: "The poppy field at the Tower is a unique and poignant focus of remembrance in this centenary year.
"It has grown rapidly in popularity, to such an extent that it is now a global visitor attraction. More on this story
