Queen Elizabeth II sends her first tweet.

The Queen sent her first Tweet today as she opened the new Information Age exhibition at the Science Museum in London.

In celebration of advancing technologies Her Majesty, 88, posted the Tweet from the official @BritishMonarchy Twitter account.

It read: "It is a pleasure to open the Information Age exhibition today at the @ScienceMuseum and I hope people will enjoy visiting. Elizabeth R."

The British Monarchy Twitter account was set up in 2009 and has 722,000 followers, but all the tweeting so far has been done by staff not the Queen herself.
