Having now watched his speech, it was o.k. I suppose he doesn't have to give policy ideas as to how to achieve the country that he wants to see, as the election is so far in the future. He sounds like he wants to be seen as a safe pair of hands, and seems to be succeeding in that aim.
I have seen on this site that left wingers are sometimes accused of a lack of patriotism, and he wanted to refute that.
I am not sure though, that implying that the party deserved to lose the last election, was a very wise move as it could well alienate the very people that campaign on the streets during an election campaign, and he will need them in the future.
Also, continually stressing the "new management " is that the way to unite the different sections in the party? I don't think so, and he needs to find a way to do that.
Those of us who were inspired by the policies under Jeremy Corbyn's leadership don't want all that hope and enthusiasm to be brushed aside.
