I think the point at the time from some callers was the way the news was released sort of covertly.
Plus, also, the new 'line' alienates others, who are quite likely to lean left and feel let down. so it remains tricky. I think they are hoping to keep it quiet.
There was an excellent caller on the subject of Scottish Labour, and Labour in general, not being left wing ,or progressive, enough and the popularity of progressive politics in Scotland, with Labours fixation on appealing to those who are fiscally and socially more conservative. I thought he was actually the most intelligent caller but I think Keir had gone by then.
