Tostig Godwinson
Harold's brother Tostig Godwinson, formerly Earl of Northumbria, now appeared on the scene; hoping to regain his titles and lands, he reportedly approached both William and Sweyn Estridsson for their support. However, since Northern England was the most suitable landing place for a Norwegian invasion, he was more valuable to Harald. Details are limited, but it is suggested Tostig sent a fellow exile, Copsig, to meet with Harald in Norway and agree plans, while he remained in France. If correct, this would also have allowed Tostig to increase both their chances by simultaneously supporting an invasion by William, who also claimed the throne.
