"Mega-canal" proposal distributed in Government

Canal running from Pennines to London would transport goods, power and water.

Aecom, an American professional services company, has proposed construction of a "mega-canal" running from the Scottish borders to London. The canal, which would cost £14bn to create, be 24m wide and run alongside a high-voltage power cable, is intended to provide solutions to future issues with water supply, power transmission and sustainable transport.

Yesterday, Construction Manager magazine reported that the proposal was implicitly supported by DECC's scientific adviser David McKay, who distributed copies to to officials at the BIS, Defra and the Department for Transport, and describes the reasoning behind it:

The canal would help to mitigate any future drought and also supply additional irrigation to the agricultural sector, by feeding Scottish water into existing waterways.

And as well as offering a sustainable alternative to road and rail freight, facilitating the movement of biomass fuel to the south, it could also carry High Voltage Direct Current (HVDC) cables in special compartments, with the water providing natural cooling.

Aecom's associate director David Weight argues that there's real hope for the proposal:

“We think that unlike HS2, local authorities would be queuing up to have a canal going through their area. As for funding, we’d anticipate a multi-stakeholder approach. There are many organisations that could either save money by using the canal or extract a toll for others to use it — for instance Scottish Power, Scottish Water, the National Grid…

The canal would also be perfect for associated developments, such as eco-towns — the power and water are already there.

The proposal is an elegant – if rather brute-force – method of combining solutions to several problems facing Britain today. Unlike the Victorian Georgian age of canals, which were primarily built for transportation of goods, Aecom envisages a greater focus being on the transportation of water, from the pennines down to the drought-ridden South East. The transmission of goods would be only secondary – although with shipping being one of the most environmentally friendly methods of transport around, it's not inconceivable that it could have a second wind.

Adding in transport of power on top, solving three problems in one, is also a very good idea. But despite that, this remains blue-sky thinking. The joined-up nature which is its greatest strength is also the single biggest reason why it's unlikely to be implemented: as good as it is at solving a number of problems, it's not likely to be the best method to solve any individual one. DECC would rather increase generation capacity; the DfT would rather focus on rails and roads; and Defra's water strategy doesn't envisage any large scale transport of water.

Instead, it's best to look at the Aecom proposal as something between a wonderful highlight of how low we now aim with our mega-projects, and porn for infrastructure geeks. With a little bit of steampunk thrown in for good measure, too – now, how about those zeppelins?

Update: @BorisWatch points out I have got my ages of canals wrong. By the time Victoria was on the throne, the railway boom had all but killed canals.

How Jim Murphy's mistake cost Labour - and helped make Ruth Davidson

Scottish Labour's former leader's great mistake was to run away from Labour's Scottish referendum, not on it.

The strange revival of Conservative Scotland? Another poll from north of the border, this time from the Times and YouGov, shows the Tories experiencing a revival in Scotland, up to 28 per cent of the vote, enough to net seven extra seats from the SNP.

Adding to the Nationalists’ misery, according to the same poll, they would lose East Dunbartonshire to the Liberal Democrats, reducing their strength in the Commons to a still-formidable 47 seats.

It could be worse than the polls suggest, however. In the elections to the Scottish Parliament last year, parties which backed a No vote in the referendum did better in the first-past-the-post seats than the polls would have suggested – thanks to tactical voting by No voters, who backed whichever party had the best chance of beating the SNP.

The strategic insight of Ruth Davidson, the Conservative leader in Scotland, was to to recast her party as the loudest defender of the Union between Scotland and the rest of the United Kingdom. She has absorbed large chunks of that vote from the Liberal Democrats and Labour, but, paradoxically, at the Holyrood elections at least, the “Unionist coalition” she assembled helped those parties even though it cost the vote share.

The big thing to watch is not just where the parties of the Union make gains, but where they successfully form strong second-places against whoever the strongest pro-Union party is.

Davidson’s popularity and eye for a good photo opportunity – which came first is an interesting question – mean that the natural benefactor in most places will likely be the Tories.

But it could have been very different. The first politician to hit successfully upon the “last defender of the Union” routine was Ian Murray, the last Labour MP in Scotland, who squeezed both the  Liberal Democrat and Conservative vote in his seat of Edinburgh South.

His then-leader in Scotland, Jim Murphy, had a different idea. He fought the election in 2015 to the SNP’s left, with the slogan of “Whether you’re Yes, or No, the Tories have got to go”.  There were a couple of problems with that approach, as one  former staffer put it: “Firstly, the SNP weren’t going to put the Tories in, and everyone knew it. Secondly, no-one but us wanted to move on [from the referendum]”.

Then again under different leadership, this time under Kezia Dugdale, Scottish Labour once again fought a campaign explicitly to the left of the SNP, promising to increase taxation to blunt cuts devolved from Westminster, and an agnostic position on the referendum. Dugdale said she’d be open to voting to leave the United Kingdom if Britain left the European Union. Senior Scottish Labour figures flirted with the idea that the party might be neutral in a forthcoming election. Once again, the party tried to move on – but no-one else wanted to move on.

How different things might be if instead of running away from their referendum campaign, Jim Murphy had run towards it in 2015.
