The British public has entered a period of mourning following the passing of Queen Elizabeth II with many expressing their grief by leaving bouquets of flowers.

Hundreds of bouquets, personal notes and candles are already being laid in memory of the country's longest-serving monarch.

The news of Her Majesty's death was announced in a statement on behalf of the Royal Family on Thursday evening.

Her death brings an end to a 70-year reign, the longest in history, having ascended the throne following the death of her father, King George VI on February 6, 1952.
