I expect the Minister will announce complete agreement between the key stake holders & that work will commence almost immediately. As she is making the statement in the Square it's going to be a good news story.
I expect that in two years' time there will be a lot of controversy about the lack of progress on the repair job. This will be blamed on:
1.) 'Unforseen' problems with the re-use of existing stone.
2.) A lack of specialist building labour to carry out the work.
3.) At least one key contractor will abandon the job for some reason.
And other issues will emerge:
Hotel operators will complain that the stalled repair job on the Cathedral is depressing bookings.
Tourists complaining that the Square is a boring construction zone as other buildings are being demolished or repaired.
