Dame Joan said: “We must never forget the selflessness of all those who sacrificed so much to keep us free during World War II.
“This is why I immediately joined up to support The Nation’s Toast. This meaningful gesture recognises the importance of not only the brave veterans who fought on the front lines but also the courageous women who put their lives on the line for this nation’s struggle.” She added: “I remember clearly coming home one morning, after spending the night in the Marble Arch underground during a particularly vicious raid, to find our block of flats had entirely disappeared and in its place, a pile of rubble.
“I stared at the faces of the ARP rescue parties, their faces drawn and soot covered, who had dug frantically all night long for survivors while I, as a child, could only think about the fate of my favourite doll who I’d left behind.”
For Mr Peek, Dame Joan’s involvement is wonderful.
He said: “She was one of the children who had to sleep on underground stations at night to avoid the bombs of the Blitz and she lived through the Second World War.
“She can appreciate the many millions of women who sacrificed so much for our freedom.
