The CPLEAR experiment uses tagged K0 and K0 produced in pp annihilation at rest to measure CP-, T- and CPT-violation parameters in the neutral kaon system. The results of these measurements and some implications are reported.

The CPLEAR experiment at CERN uses time-dependent decay-rate asymmetries between K 0 and K 0 to measure η +− . The analysis and the systematic errors are discussed. The preliminary results from all our data are φ +− = 43.5 0 ± 0.5 0 stat ± 0.

The CPLEAR collaboration has constructed a detector at CERN for an extensive programme of CP-, T- and CPT-symmetry studies using ${\rm K}^0$ and $\bar{\rm K}^0$ produced by the annihilation of $\bar{\rm p}$'s in a hydrogen gas target. The ${\rm K}^0$
