These constant smears on Corbyn, and the Labour Party generally, is nothing new.
It has been happening since 1945 when Winston Churchill made what most commentators believe was a major miscalculation in declaring that "the Labour Party would have to employ a form of “Gestapo” to implement its policies". This was followed up by a tabloid headline replicating those words.
It continued with the vicious media attacks on Michael Foot, who some years later won substantial damages for a libellous story printed by the Sunday Times and the News of the World that he had been a KGB spy.
During Kinnock's election campaign the attacks from the right wing media was relentless, as an article by Roy Greenslade in 2002 detailed:
"By the time he fought his first election, in 1987, he was being persistently portrayed as a weak and incapable leader. But it was nothing to the demonisation of Kinnock which followed in the years leading up to the 1992 election.
............
"On the eve of his visit to the White House several papers carried a story about Kinnock attacking Bush ..... It was, a tabloid journalist confessed to the Sunday Times correspondent, "pure invention".
A common theme was that Kinnock was unduly influenced by his wife who, the Sun presumed, was far to his left: "Is Glenys a Red in Neil's bed?" ..............The Sunday Times ran a story which maintained he had contacts with the Kremlin at the height of the cold war.............Editor Andrew Neil was forced to concede that the paper's boast of "Kinnock's Kremlin connection" was inaccurate. ............Two days before the election the Sun published nine pages bearing the slogan "Nightmare on Kinnock Street", including a page in which a "leading psychic" asked dead world leaders to name who they would vote for. Kinnock got Stalin's vote; Major picked up Queen Victoria."
Then, again, when Ed Miliband fought the election, the right wing press was out in full force, using ridicule and innuendo to present him as a dishonourable figure of fun, and describing his father, who had served in the Royal Navy, as "an enemy of Britain".
With regard to Corbyn and the current round of smears and ridicule, the Huffington Press reports that he has received the following apology and "substantial" damages from Ben Bradley (the man who said unemployed men should be vasectomised):
" “I accept that I caused distress and upset to Jeremy Corbyn by my untrue and false allegations, suggesting he betrayed his country by collaborating with foreign spies.
" “I am very sorry for publishing this untrue and false statement and I have no hesitation in offering my unreserved and unconditional apology to Jeremy Corbyn for the distress I have caused him.” "
Do not kid yourselves that what we have at the moment is a "free press". It is, for the most part, a propaganda machine.
