Wilko has proposed the closure of up to 15 stores this year, threatening more than 330 jobs with a union branding it another “nail in the high street’s coffin”.

The Nottinghamshire-headquartered company said it follows a review of the 414-strong portfolio, and does not impact on new store or store relocation programmes.

Negotiations with landlords could save some, but dates as early as next month have been given for many.

It said that as an established business with more than 90 years trading, it has many ‘legacy’ locations and has identified some outdated lease agreements.
