Keir Starmer can be as credible as he wants, but the reason Labour lost the last election, apart from shifting too far to the left, was because they pandered to the London liberal elite and betrayed their core voters in the Northern heartlands, 'leave' voting country.
His cabinet today consists entirely of remainers. It's fair to say some people never learn.

London Liberals is irrelevant and figment of your imagination. They are not Liberals. Liberalism is a mix of nothing that makes much sense especially compared with Labour.

What the Tories intend to do now is the same as the Blare/Brown aims. Many areas of the country need it people who think it's just the north are living in cuckoo land.
Corbyn's mistake was not explaining well enough but given what a lot of the public seem to expect from politics, all nice and simple when it isn't that must be tricky and rather unusual. Privatisation in some areas is not producing what it is intended to do - price control via competition. He wasn't saying all just some. Also some lacking the efficiency privatisation is supposed to provide. Plus ever increasing debt levels in some areas. He's also saying that no private company can do what is needed as costs are too high and a lot would need borrowing who ever did it. Gov costs in that area are much lower than business. The end user pays for it. Also dividends and any tax that is is collected. Tax collected figures rather highly in reports on why privatisation is a good idea. Who pays it us - indirect taxation from what are near monopolies in real terms. They can charge what they like.
If done there are indications that state ownership wouldn't be as it usually is. More like what Brown did in some areas - out of political control. It wouldn't surprise me if this lot went in the same direction in some way or the other.
Personally I will never forgive Blare for the M6 toll road while mentioning a new free motorway for the SE. That's politics though, aims fine but reality can differ in rather unexpected ways.
