Based & tallinnman - apologies if I offended either with yesterdays robust tirade - got a bit carried away.
gate 22 - your views are very well documented as the leading member of the Aldergrove Appreciation Society. The point about shopping centers was meant as an example. The point being that competition is not stiffled because there is capacity at another location. The ports example is more relevant.
Nevertheless Lisburn - Sainsburys & Tesco 1 1/2 miles apart, Forestside 1/2 mile apart, Craigavon - inside same shopping centre. Announcement this week of new Sainsburys in Newtownards close to tesco. All recent example of where planners decided that competition (between private companies) should not be stifled because the sitting incumbent didnt like it.
Regarding the John Lewis store it has not been built purely due to the Belfast lobby afraid of competition. If it is not passed at public enquiry it sends out a clear message that only commercial development is allowed if there is no impact on the belfast lobby. ironic in the context of discussion about expansion of a 'Belfast' airport.
