So you are admitting that you're advocating that work be limited to English firms on entirely protectionist grounds and that your comments on environmental benefits were completely meaningless?
What's this got to do with it?
What's the environmental impact of transportation of difficult cargoes, then?
1, not entirely, but everything in situations of huge importance needs to be considered, financial, environmental, and logistical, just because there are more reasons doesn't make the other reasons completely meaningless clearly.
2, it's an example from a long list of unfair bonuses for devolved administrations that range to almost everything, the bus pass age is another discrimination.
3, Newport would find it difficult adjusting to manufacturing steel rails quickly, Scunthorpe already does this, so there would have to alterations to the plant and extra movement of wagons to be in place if it were chosen etc.
Scunthorpe is just simplest choice in every way, all nations should prefer their own domestic industry in any field if they can, whether they are in a union such as the UK or EU shouldn't change that fact.
