That's what his opponents keep repeating, but they're not able to show much in the way of evidence.
Have you heard his performance at PMQs ?
He consistently misses easy targets and failed to take David Cameron to task on a variety of key subjects.
Cameron has had an easy ride - May will enjoy a similarly easy time at the dispatch box.
Wider than that, Corbyn has provided an easy target for the press. Press coverage has been all about Corbyn instead of the government or Labour's opposition to that government (contrast that with Nicola Sturgeon who has kept some pressure on the government).
He's completely lost control of, and the support of, the parliamentary Labour Party. He has failed to persuade, threaten or cajole those MPs around to his position.
Sure, opinion polls are bad for Labour right now, but that's because of the turmoil caused by the Labour rebels. Before they launched their recent coup attempt Labour were doing okay in the polls, and if the MPs had solidly supported their democratically elected leader from the outset then Labour would probably have been doing better still.
Even if the Labour Party was riding high in the opinion polls, it's an irrelevance until we have another general election - currently scheduled for 2020. Until then Jeremy Corbyn has an important job leading the opposition which includes:
- Vigorously challenging the PM at PMQs
- Providing clear leadership for the Parliamentary Labour Party
- Inspiring, motivating and persuading a key part of the UK population to consider Labour Party policies which in turn will pressure the government to change their policies to capture that support
- Provide a rallying point for anti-government sentiment
I don't think he's doing a good job at any of that.
It's shameful that these old Blairites hold their own narrow self-interest higher than the interests of the party they ride on the back of.
A violent lurch to the left isn't going to capture the hearts of the UK population IMO. With the exception of Scotland (where the post independence referendum label of "Red Tories" was very damaging), the problem wasn't that the Labour Party wasn't left wing enough. Instead the problems were:
- It was perceived to be too left wing - specifically too reckless in spending
- The leader lacked charisma
Jeremy Corbyn doubles and redoubles on both of those issues and adds a whole extra layer of a dubious past in which he has been a vigorous supporter of the IRA,
