Task: Question Answering
Input (English): Passage: The political situation in England rapidly began to deteriorate. Longchamp refused to work with Puiset and became unpopular with the English nobility and clergy. John exploited this unpopularity to set himself up as an alternative ruler with his own royal court, complete with his own justiciar, chancellor and other royal posts, and was happy to be portrayed as an alternative regent, and possibly the next king. Armed conflict broke out between John and Longchamp, and by October 1191 Longchamp was isolated in the Tower of London with John in control of the city of London, thanks to promises John had made to the citizens in return for recognition as Richard's heir presumptive. At this point Walter of Coutances, the Archbishop of Rouen, returned to England, having been sent by Richard to restore order. John's position was undermined by Walter's relative popularity and by the news that Richard had married whilst in Cyprus, which presented the possibility that Richard would have legitimate children and heirs. Question: Who refused to work with Puiset?
Output (English): Longchamp
