I think those lawsuits are over mistaken identity. The British left found a name of someone apparently involved in this back in the 1980s. There was a Tory MP from the same time period, who has now been made Lord something or another, and they ran stories with the idea that they were one and the same person. Turns out it was two different guys with the same name. A number of lefties had posted gleeful comments on Twitter, and he has sworn to sue every one.
Something like 5 pounds and a written apology.
