May 22 (Reuters) - The department store chain Dillard's

sued Wells Fargo ( WFC ) on Thursday, saying the bank

repeatedly breached a since-abandoned co-branded credit card

relationship, causing the department store chain tens of

millions of dollars in losses.

Dillard's filed its lawsuit in Manhattan federal court, less

than a year after being "shocked" to learn that the

fourth-largest U.S. bank had decided to abandon the co-branded

card market.
