Morgan and opposition parties have been pressing the UK government to give Wales a slice of the cash spent on the HS2 high speed rail project in England.
They believe UK government’s funding rules, known as the Barnett Formula, should mean a dividend for the Welsh government, something ruled out by the previous Conservative government at Westminster.
On Friday, Sir Keir also ruled that out, telling BBC Wales: “I want to deliver for Wales, but actually heavy rail, if you like, the heavy infrastructure, that’s not devolved, and therefore the Barnett rules don’t apply.
“We are already sitting around the table with the Welsh government on rail infrastructure that is important across Wales, because we need to get on with that.
“And so we’ll do that, and that’s really the game changer.”
