Labour’s new manifesto has echoes of the past

Mr Corbyn predicted the policies would prove “very popular” and said they amounted to “an offer that will transform the lives of many people in our society and ensure that we have a government in Britain on June 8 that will work for the many, not the few, and give everyone in our society a decent opportunity and a decent chance, so nobody is ignored, nobody is forgotten and nobody is left behind.”

The version of the manifesto leaked to the media included commitments to bringing Royal Mail back into national ownership, establishing publicly-owned bus companies and extending the HS2 rail line from its proposed end in Yorkshire to Scotland.

It promised a “presumption of devolution” that would see powers returning from Brussels after Brexit handed to regions rather than Westminster and a commitment that areas would not have to agree to having metro-mayors as a condition of taking more control over their own affairs.

The draft also contained previous promises including a ban on fracking, maintaining the economic funding regions such as Yorkshire currently receive from Brussels after Britain leaves the EU.

But the document threatened to re-open the row over Labour’s position on Europe by suggesting that “‘no deal’ is the worst possible deal for Britain” and the party would “reject ‘no deal’”.

The wording suggests a Labour government could decide Britain should remain in Europe in the event no deal with Brussels could be reached.

Earlier this week, Mr Corbyn insisted the Brexit question “is settled” but was later reluctant to agree the UK would definitely be leaving.

The draft document split opinion among Labour candidates with one telling The Yorkshire Post policies such as renationalising the railways would prove popular with voters angry that the East Coast rail franchise, which had been profitable during a period of public ownership, was privatised under the Coalition.

But others feared the scale and costs of the proposals could play into Conservative hands.

One said: “There are few things that will convince those we failed to convince last time.”

The draft left Labour facing fresh questions over how it will pay for the commitments.

It included previously announced plans to raise corporation tax and proposed an “excessive pay levy” on companies with “high numbers” of well-paid staff.

In an email to Conservative supporters, Chancellor Philip Hammond said: “Labour’s leaked manifesto makes it clear: while Theresa May wants to take our country forwards, Jeremy Corbyn wants to drag us backwards.

“The stakes at this election just got higher.”
