Falmouth, Cornwall

In September 2016 Sainsbury's put the plans for Ponsharden on hold. Having already opened a small store in the former Leo's supermarket, Sainsbury's gained planning permission in 2011 to build what would have been one of the biggest stores this side of Bristol.

Work was due to begin in 2012, but the scheme was pushed back a number of times until the company said last year it was reviewing all its proposed developments following changes to the market.
