The Queen's 90th Birthday

21st April 2016 marks Her Majesty the Queen's 90th birthday. On this day, together with His Royal Highness the Duke of Edinburgh, the Queen embarked on a walkabout through the town to greet well-wishers, as she became the first reigning British monarch to celebrate this milestone.

Kirsty Young presented live coverage of these celebrations and Sonali joined the BBC Events team as a reporter outside Windsor Castle on this special day.
