We have performed a partial-wave analysis of the K{sup +}K{sup 0}{sub s}{pi}{minus} system produced in the reaction K{sup {minus}}p {yields} K{sup +}K{sup 0}{sub s}{pi}{sup {minus}} {Lambda}/{Sigma} at 8 GeV/c. We present results of a preliminary analysis of approximately 2000 events in the K{sup {minus}}K{pi} mass range 1.24--1.64 GeV, with 0.0 < {minus}t < 1.4 GeV{sup 2}. In the 1.28 GeV mass region, we observe a small J{sup PG} = 0{sup {minus plus}} contribution but little indication of a 1{sup ++} wave. We observe a large enhancement of events at the threshold of KK* production. Above this threshold the J{sup PG} = 1{sup {plus minus}}, 1{sup ++} and 0{sup {minus plus}} waves all contribute, and we see evidence for a 1{sup {plus minus}} resonance below the KK* threshold. 7 refs., 9 figs., 1 tab.
