WASHINGTON (AP) _ The CBS affiliate in the Washington area, WUSA-TV, mistakenly began its ''Face The Nation'' broadcast Sunday with last week's preview of the New Hampshire primary.

Commentator Lesley Stahl started the show with, ''Welcome to 'Face The Nation,' this is Lesley Stahl in New Hampshire,'' and spoke of what would happen in last Tuesday's primary.

The error was not detected until more than five minutes into the show.

At that point, Republican presidential candidate Pat Robertson was talking about prophecies concerning the ''forces of evil'' in the world and an embattled Israel. The tape was abruptly cut, and the show picked up with Ms. Stahl in mid-sentence asking Israeli Defense Minister Yitzhak Rabin about Israeli forces being out of control in the West Bank.

Diane Digit, WUSA publicity manager, said as soon as engineers realized they were mistakenly running last week's show, they switched to a tape containing the correct broadcast.

CBS affiliate stations around the country tape the weekly show from a feed transmitted by the network's New York office, she said.
