Measurements of neutral current four fermion events                            
in e+e- collisions at LEP2                                                     
  
Final states from neutral current four fermion events are analysed.            
Total and differential event rates are compared with the Monte                 
Carlo predictions.                                                             
The data correspond to a total of about 440 pb^-1                              
recorded with the OPAL detector in the years 1997 to 1999                      
at center-of-mass energies between 189 and 202 GeV.
