Search for New Physics in Rare B Decays                                        
  
A search for the decay  B+ --> K+ K+ pi- was performed using data collected    
by the OPAL detector at LEP. These decays are strongly suppressed in the       
Standard Model but could occur with a higher branching ratio in supersymmetric 
models, especially in those with R-parity violating couplings.                 
No evidence for a signal was observed and a 90% confidence level upper         
limit of 1.29 x 10^-4 was set for the branching ratio.
