When will the media realise that repeating lies will never make them truths?

In Jan 1987 The Times ran with a story about Jeremy Corbyn giving money to an on-the-run terrorist, which was subsequently acknowledged by The Times to have been wrong. The Times issued an apology. Time passed. Today those other bastions of news, The Sun and The Mail reported the same story as was carried in the 1987 issue of The Times, despite it being proved to be wrong in 1987!

Checking the IPSO Editors' Code of Practice it seems this is a clear breach of Clause 1 Accuracy 

i) The Press must take care not to publish inaccurate, misleading or distorted information, including pictures.

ii) A significant inaccuracy, misleading statement or distortion once recognised must be corrected, promptly and with due prominence, and - where appropriate - an apology published. In cases involving the Regulator, prominence should be agreed with the Regulator in advance.

So why did The Mail and The Sun print a story which The Times (owned by News UK as is The Sun) knew was factually incorrect? There is only one reason: it is yet another disgraceful attempt by the media to discredit the new leader of the Labour Party.

I would expect a correction with due prominence to be published along with an apology by both The Sun and The Mail!  My feeling is that won't happen, but shame on them both if it does not!
