PARIS, Nov. 26 (Reuters) - French call-centre operator Teleperformance (ROCH.PA) cut its guidance for 2009 on Thursday, warning that price pressures and poor performance in its home market would drag down like-for-like sales and profits.

"We have a weakness and, unfortunately, it is France," said CEO Jacques Berrebi, during a conference call.

"France represents 80 percent of our company's problems," he added, though the country only accounts for 13 percent of its revenues.
