Neutral Higgs bosons of the Standard Model (SM) and the MinimalSupersymmetric Standard Model (MSSM) were searched for in the data collected in1999 by the DELPHI experiment at centre-of-mass energies between 191.6 and201.7 GeV with a total integrated luminosity of 228 pb^{-1}. These analyses, incombination with our results at lower energies, set 95% confidence level lowermass bounds on the Standard Model Higgs boson (107.3 GeV/c^2) and on thelightest neutral scalar (85.9 GeV/c^2) and neutral pseudoscalar (86.5 GeV/c^2)Higgs bosons in representative scans of the MSSM parameter space. An extendedscan of the MSSM parameter space was also performed to test the robustness ofthese limits.Comment: 49 pages, 19 figures, Accepted by Eur. Phys. J.
