Manch Approach staying at Manchester.
Last I heard, the 'desperate' units for staff on the airports side are Heathrow (apparently losing staff to the ME), Glasgow and Edinburgh. Therefore, expect postings to Southampton, Aberporth and Birmingham or some other such cock-up!
In seriousness though, apparently Heathrow, Edinburgh, Glasgow, Manchester and Gatwick are all more short than others (happy to be corrected) so presumably that's where the recruits would go?
