An old article.prior to the Labour Party leadership election, but it outlines why Anniebach and other Labour party stalwarts despair. Later in the article it states that 'many local parties were ripe for takeover.' It happened.
" The battle for Labour: MPs must surrender to Corbyn or leave
Labour party representatives have been accusing the hard left of “entryism” in the run up to the leadership election next month.
The party’s deputy leader, Tom Watson says he has evidence that members of the Socialist Party and the Alliance for Workers’ Liberty are signing up as Labour members. Watson claims that these groups – previously known as Militant and Socialist Organiser – are using the methods used by Militant in the 1980s to take control of local constituency Labour parties (CLPs).
Militant’s tactics were to take over moribund constituency parties by the simple expedient of joining the party, getting themselves elected to local committees and then boring and antagonising more moderate members into resigning. This so-called “entryism” was how local parties fell under Militant control."
and
"Moderate MPs complaining about hard-left entryism should also recognise that many local parties were ripe for “take over”. A large number were small (in 2012, the last year for which we have data, more than one-third had less than 200 members, only 9% had over 500) and engagement with party democracy was generally low. Moderates in the party had themselves to blame for that state of affairs."
I think it's interesting that many quickly forget the chaos and disarray of the Labour Party, (well after the leadership crisis) less than a year ago.
Theresa May's disastrous call for an election earlier this year (which the Conservatives still won) allowed Corbyn and his supporters to claim a 'victory' and all of a sudden Corbyn was the man - even though his leadership divided the Labour Party. Theresa May unwittingly poured oil on Labour's troubled waters.
Now we are supposed to believe that the party is united and all the rifts have healed?
Very few MPs would stand by Corbyn a year ago. Many distanced themselves, quite vocally and the call for a new leader made news headlines night after night, month after month. Those rifts remain, in Westminster and at grassroots level.
