This paper describes recent measurements of the tau lifetime and leptonic branching ratios, concentrating on results from DELPHI at LEP but also mentioning results from other experiments, in particular those from other LEP experiments. The DELPHI analysis is based on around 6500 [tau][sup +][tau][sup [minus]] pairs in the barrel region, taken in 1991. The combined LEP results show that the ratio of the tau to muon Fermi coupling constants is consistent with unity.
