In The Official Albums Chart, Forces sweetheart Dame Vera Lynn has become the oldest living artist to top the chart with We'll Meet Again - The Very Best of Vera Lynn.

The Dame's album has been steadily climbing the chart for weeks and has surprised the 92-year-old, who knocks last week's No.1 Arctic Monkeys from the top spot as well as keeping The Beatles from getting to the top with their remastered albums.
