For Labour to win the next UK election, the "right-wingers" that tried to remove him as leader must accept him as the leader, and his policies too, and stop trying to find fault with him.

If they had given him support before, Labour might have won this time.

They have now more or less recognized he can lead the party, but some of them are still attacking his traditional Labour policies and demanding more right-wing policies. Corbyn can surely judge better than I, but it seems to me that they will never really support the revived Labour party.

We have a similar problem in the US, with the right-wing "centrist" establishment Democrats. Sanders says they have learned nothing from their defeat, and are still fighting to keep Wall Street in power.
