It appears to me that the possibility of delays now could be a problem for cas, other sites, other supermarkets, objectors etc etc.
What it doesn't prove though is that it won't still happen, and anyone who says another supermarket or two cant be developed at once or in close proximity clearly doesn't understand the power of the supermarkets.
Look at Wakefield, Tesco's sniff around mention they want the old Sainsburys site, Sainsburys kick off and Wakefield ends up with a new Tesco and ANOTHER Sainsburys all within a mile of the city centre, on the same road, and i would argue that the people of Wakefield don't need either.
