You know exactly what I mean !
Sorry Miss M, but I don't. Why would I ask a question if I already knew the answer

You need to spell it out to me: by referring to 'transferring subjects to another campus' did you mean Buxton Lane or Cheadle?
So why are we already losing curriculum at Marple?
There are various possible reasons. The most common reason for a course being dropped is that not enough students want to take it - this happens all the time: courses for which there is little demand are replaced by new ones that students actually want to do. It's called being responsive to changing demand. The one certainty is that any course which is closing at the moment won't be doing so because of the possible future closure of the Hibbert Lane site, which is far from a done deal, and, contrary to what you and Finetime seem to believe, is likely to be a few years away, if it happens at all.

However as far as Asda is concerned if they put their planning application in a day after local elections in May and SMBC's Planning Committee nods it through then there is no reason why you can't be patting yourself on the derriere as you walk through the doors whistling the asda price jingle by next Easter. And before anybody starts jumping up and down saying the Council have made a public statement that they will refuse planning permission - well they have said no such thing - the Director of Planning has and so has the leader of the Council (who incidentally has a good chance of losing his seat in May) but they aren't the Council - they're just a couple of people involved with it.
....but s/he may be unaware that there is no serious prospect of the SMBC Planning Committee 'nodding through' a planning application for a supermarket in Hibbert Lane, either before or after the May elections, for the simple reason that the Local Development Framework has the area zoned for housing, not retail. So if a planning application for retail use is going to be approved, it will be at appeal - and that's a long-winded process. And then
if the application were ultimately to be approved - say, some time next year - the College would then have to get planning consent for its Buxton Lane development, and then build it and move in, before the demolition team goes on site at Hibbert Lane. So don't expect much back-pocket slapping until about 2016 at the earliest!
