Cowgill said: "When you go into administration you have a clean sheet for renegotiating rents. In some areas, [Blacks] is over-rented on a number of stores. If landlords are more realistic then the future of retailers such as Blacks is more secure." JD, which also operates chains including Bank and Scotts, said underlying sales in the UK and Ireland rose by only 0.1% in the five weeks to January 7 - its seventh consecutive year of growth. But sales at fashion chain Bank were hit by "distribution issues" with suppliers of brands over the period, although Cowgill would not elaborate on this.
