After Jackdaw, how much political damage would approving Rosebank do to Labour?

I think the government is seriously underestimating the political fallout from Jackdaw, especially with Rosebank still on the table.

It feels like they're treating new oil and gas approvals as something they can push through in the name of growth and then move on from. But approving Rosebank would be an even bigger decision, and the opposition to it isn't just going to disappear.

How much political damage do people think another approval would actually do?
