  Diffractive photoproduction of rho, phi and J/psi was studied in the BFKL
approach to hard colour singlet exchange. Differential cross sections, the
energy dependence and spin density matrix elements were calculated and compared
to data from HERA. The overall description of data is reasonably good, except
of the single flip amplitude which has the wrong sign. Importance of chiral odd
components of the photon is stressed.
