Labour conference votes to put pledge to introduce proportional representation in manifesto despite Starmer ruling it out – as it happened

Loud cheering as motion on PR is carried even though Labour leader says he will ignore vote. This live blog is now closed.

In June, as the RMT union launched what has become an ongoing series of strikes, Keir Starmer ordered Labour frontbenchers and shadow ministerial aides not to join picket lines. This infuriated leftwing Labour MPs and some union leaders, notably Sharon Graham, the general secretary of Unite.

At one point it looked as if there might be a huge row at conference about whether shadow ministers should or should not be allowed to join picket lines. But, in an interview with the Today programme this morning, Graham suggested that a truce of sorts has been agreed - even if the two sides do not entirely see eye to eye.

My issue about this ... isn't necessarily around one person on a picket line because, quite frankly, that isn't the issue. The issue is the mood music [ordering shadow ministers not to join picket lines] suggests. It suggests a mood music that being on the picket line is somehow a bad thing. It's a naughty step situation.

The party who is there to stick up for workers should not give the impression - that's the problem, it gives the impression - that they are saying picket lines are not the place to be. And I think that it was unfortunate. I think it was a mistake. I think, to be honest with you, Labour knows it was a mistake. And I don't actually think it's holdable.

When people go on strike it is a last resort at the end of negotiations. And I can quite understand how people are driven to that ... I support the right of individuals to go on strike, I support the trade unions doing the job that they are doing in representing their members.

I'm incredibly disappointed that as delegates we've been excluded from this key part of the conference's democratic process.

This is an unprecedented move silencing members' voices. Our CLP sent us here to Liverpool to promote our motion on public ownership and a Green New Deal, but we've been unfairly denied that right.
