Abstract
We summarise the latest experimental QCD studies based on data from LEP. Measurements of the quark and gluon jet fragmentation functions are discussed, including a new algorithm to infer the properties of unbiased gluon jets. We describe a new test for destructive interference in the radiation of soft gluons from a three-parton system. Finally, we report the latest combined value of the strong coupling, measured using event shape observables.
