Crowds Gather for Queen Mother

Britain Celebrates Queen Mum's 100th birthday

The Queen Mother celebrates her 100th birthday in grand style on Friday, becoming the Royal Family's first centenarian.

In a day of festivities, the oldest British royal will take the nation's salute from the balcony of Buckingham Palace.

She will be cheered by thousands of well-wishers, many of who have camped overnight to ensure they are part of the historic occasion.

To mark her mother's 100th birthday, the Queen has issued a special Honours List recognising nine people, five of whom helped stage the Queen Mother's centenary pageant last month.

The Queen Mother's life has spanned the milestones of the 20th Century and embraced a new millennium.

As possibly the best-loved member of the Royal Family she has been a symbol of grace in an era of upheaval for many millions.
