Tesco has been refused planning permission to have a temporary marquee in the car park of its Lake Road store selling seasonal goods for six months each year.
The retail giant had applied for planning consent (13/00687/B) for the erection of the temporary building for seasonal retail sales on an annual basis between April 1 and September 30.
A marquee has been erected previously in the car park at the Lake Road store selling summer goods.
But the planning committee refused the application, saying that it could undermine the viability of existing shops in Douglas town centre.
In its decision, it said Tesco’s application conflicted with the long-standing policy of not directing retail development away from the town centre.
It said: ‘The proposal would conflict with the business policy of the Strategic Plan which states that retail development will only be permitted in established town and village centres, in the interests of safeguarding their vitality and viability.
‘The planning authority is further concerned that to permit the development would set up a unwelcome signal and precedent for further expansion of the supermarket site to the potential detriment of the vitality and viability of Douglas town centre.’
