Earlier, she said: "It's a huge privilege to go out to Arras and represent the family, and to lay a wreath.

"It will be quite poignant. I will go and see his grave at Duisans cemetery and lay flowers there.

"I think my father would be very proud and happy that one of his family will be there at the ceremony. It will be a very emotional day."
