A tweet by comedian Alan Davies could cost him as much £200,000 in damages - almost half the number of people to which he retweeted a false allegation linking Lord McAlpine to a child abuse scandal last year. The 47-year-old wrote to the former Conservative party treasurer to apologise after he tweeted "Any clues as to who this Tory paedophile is...?" to over 400,000 followers and retweeted a reply which named Lord McAlpine.
