The Alice in Wonderland star recorded a message in aid of the City of London Poppy Day, a drive to boost donations to the Royal British Legion, which helps war veterans and their families.
She declared, "Hello everybody, it's Barbara Windsor here and I, together with Transport for London, am supporting London Poppy Day on the 1st of November. Please, please give generously."
Windsor has previously stated, "I'm thrilled to be standing shoulder-to-shoulder with those who serve and (to be) helping to raise awareness of London Poppy Day. It's an absolute honour to be the voice of the Tube on the day."
