Creating the Field of Remembrance at Westminster Abbey

Every year a sea of scarlet poppies is unveiled in the grounds of Westminster Abbey, in tribute to those killed in battle.
This year's Field of Remembrance contains over 100,000 crosses, sent by supporters of the Royal British Legion and planted by volunteers.
BBC News met Leah Harris from the Royal British Legion, and volunteer Russell Bayley, as they made the final touches to the display.
