Update (11 October 2015)
On 11 September 2015, Lidl submitted a full planning application (15/04194/FUL) which appears to occupy a substantially larger footprint and with more parking/loading and retail space than signalled when Lidl representatives presented to LCCC in 2014 and – apparently – to local residents earlier this year. Objections and comments need to be submitted by 16 October 2015.
