Discount retailer TJ Morris aims to break the 100-strong barrier this year with value chain Home Bargains.
Retail operations director Joe Morris said another 15 Home Bargains stores will open this year, as the company pushes beyond its Northeast heartland.

In the year to June last year, sales increased from£117 million to£141 million.
Pre-tax profits slipped from£7 million to£6.7 million.
