So -
www.onerailton.co.uk is the website for One Lambeth Justice which is pursuing the court case.
https://twitter.com/OneLambeth_Just is the twitter account linked to on onerailton.co.uk and describes itself as "This is the official account of residents fighting the social injustice of LTNs in Lambeth whilst supporting the legal campaign."
However, "One Lambeth Justice" the legal campaign does not recognise "One Lambeth Justice" the twitter account as being connected and has no control over it.
Meanwhile the twitter account
https://twitter.com/LambethOne (OneLambeth) is not connected with
https://twitter.com/OneLambeth_Just (One Lambeth Justice) and says:
"The
@OneLambeth_Just account is not affiliated with, and is run autonomously from,
@LambethOne. It is not involved in the campaign to change Lambeth to a committee system. We condemn the inflammatory language repeatedly used by that account, and have reported it to
@Twitter."
