A former aide to Jeremy Corbyn has lost an appeal against a High Court libel ruling which ordered her to pay £10,000 damages to television presenter Rachel Riley after a Twitter row.

Ms Riley, 36, who appears on the Channel 4 show Countdown, won a claim against Laura Murray, who is in her early 30s and used to work for the former Labour leader, in December last year.
