I see this turned into a bash the Farage thread. Legally there was a weak case against Brand, she didn't name the victim of the joke (if you can call it) but alluded to them. Nor could she have dome anything without the BBC faciitating its public dissemination, because I doubt this was a live broadcast. It is therefore the BBC who would face any such prosecution and almost certainly the reason, the joke was edited out when the programme was repeated.
However, given the earlier defensive of the joke, what it does illustrate all too well is that a public broadcasster is not the least bit sensitive to the subject of attacks on people, if they are seen as being right wing. Litte wonder that the programme maker David Baddiel, idenitifies himself as a prpgrassive left wing comedian. In this BBC interview he defends the joke without apology and says it was part of Jo Brands repertoire against people she "hates" Since when did hate be a worhty subject to condone rather than mock and ridicule, through the medium of humour by the BBC?
For most people it isn't about freedom of speech but why this was seen fit to be made the subject of light entertainment by the BBC, if it passes their political acid test. It's not Jo Brand in the dock with this, it's the BBC and bias broadcasting
