LONDON (AP) _ Former world featherweight boxing champion Barry McGuigan is urging other British fighters to form a union to protect themselves from unscrupulous managers and promoters.

The Irish-born fighter, who took the World Boxing Association title from Panama's Eusebio Pedroza in 1985, told the British Broadcasting Corporation on Wednesday that some boxers were forced into a ''slave's contract'' with managers.

''We need a union so we can go to the Board of Control and say we want changes made,'' said McGuigan, who defended his title twice but retired two years ago. ''Every other sport has one ... why not boxers? I don't want to see this frustration continue for the next ten or twenty years. We want to change it now.''

AYLMER, Quebec (AP) - The names of world figure skating champions Paul and Isabelle Duchesnay will live on in their home town.

In August, a street will be named Rue Duchesnay to honor the brother-and- sister team who won their first world ice dance championship in March.

The skaters unveiled the street sign Tuesday at a reception in their honor. The sign will be located only a stone's throw from their parents' home.

Aylmer Mayor Constance Provost also presented the Duchesnays, who skated for a nearby Ottawa skating club before moving overseas in 1985 to represent France, with paintings by local artists Jacques Desgagnes and Chantal Gauthier.
