POGS in response to your posts @ 17:32 and 17:40 today (05/02/18) then I feel that you and others on this forum do not recognise or accept the fundamental changes that have come about in the Labour party and the broader Labour movement in recent years. Jeremy Corbyn did indeed vote against the Labour leadership many times during the Blair/Brown era. However, those "rebellions" were rarely reported in the media and Corbyn never tried to make that otherwise.
In the above, those that are causing the current problems in the parliamentary Labour party continually draw the attention of the media to their activities, and that has caused huge resentment against them within the party and the broader Labour movement in the country.
It also has to be seen that since the electoral defeats of 2010 and 2014 the trade unions, primarily through their grassroots activist, have been determined that never again shall it be that they will fund a Labour party that has no commitment to their interests such as that which occurred during the twelve years of Blair/Brown government. In that, not once did Blair ever address any trade union conference and not one section of the numerous Thatcher anti-trade union legislative acts was rescinded.
However, with Corbyns election as leader of the Parliamentary Labour party, he backed the unions and other rank and file demands for far greater democracy in the party. Therefore the Labour National executive has been greatly expanded to include many more who represent the Broad base of the movement, and the annual conference has been expanded similarly to add many more of the above representatives.
Therefore and as stated, the present Labour party is not in any way similar to the party of Blair and Brown or even that of Edd Miliband as its leader. The fundamental changes that have been brought about will not be reversed in my opinion, and those that cannot accept those changes are most certainly unwelcome in the party.
Further in my opinion (for what it is worth) even if the Labour party were to be defeated in the next general election, still things would not change. In that, the grassroots of the of the movement most definitely feel that in twelve years of government they received nothing from a Labour party administration they financed throughout that time. Indeed they witnessed Blair and his cronies "cosy up" to the bankers that brought this country to its knees in 2008.
To add to the above, the trade unions have achieved in the last eighteen months significant victories through the courts in regard to people employed in the Gig Economy. Although that battle is not entirely over at this point in time, it is i believe making those unions wonder if the Parliamentary party is as essential to their future as has been believed for very many years. The Gig Economy has been seen as the most significant threat to the trade union movement in recent times. Should they bring about the end of that those awful employment conditions without the aid of Parliment or the parliamentary labour Party, then a big change of attitude and in that rank and file policy could be on the cards?
I feel that first evidence of that change may have seen yesterday when Jeney Formy told the NEC and the parliamentary Labour Party some home truths regarding anti-semitism in the movement that many did not wish to hear.
For the future watch that space, or should it be that office.
