This from the RMT...
"RMT can confirm that we have today commenced a High Court action for
defamation on Boris Johnson over his Not Ken Again poster campaign
which falsely portrays our General Secretary Bob Crow as being part of a
culture of political immorality and as having caused serious harm to
the interests of people in London.
"RMT will be making no
further comment and will be giving no interviews on this matter as it
proceeds through the legal process."
