The Conservative party has outspent Labour in its Facebook campaign to win Cardiff North – a key marginal which sees Labour’s Anna McMorrin defending a slim 4,171 majority. However, like in other marginals, money from unofficial, non-party, sources has closed the Facebook advert spending gap – this time in favour of Labour.
Meanwhile, the Tories have angered some voters in the constituency by parachuting in a candidate and paying for a letter to be circulated from an ex-Labour MP encouraging people to vote against Corbyn.
On Facebook, one of the major digital campaign battlegrounds, McMorrin's own page has spent only £165 between 1 October and 9 November, and Llandaff North Labour has spent £214.
