Twitter birthday: Six tweets that failed

It is the tenth anniversary of the first tweet.

Over the past decade, politicians have become fond of using the service to build their public image, whether it's arguing about policy or providing little bon mots of personal life, to show they are as human as the rest of us.

BBC Monitoring looks at some of the more amusing political gaffes over the years and tells you how not to fail on Twitter.
