We study the possible connection between centre vortices and P-vortices in SU(2) gauge theory. After briefly recalling some essential properties of centre vortices we point out that there is no known a priori connection between the gauge dependent P-vortices and the gauge invariant centre vortices. We then show by Monte Carlo simulations that the 'centre projected physics' strongly depends on the gauge copy from which the maximal centre gauge fixing is started. This reveals the presence of Gribov problems, and casts some doubts on the physical meaning of P-vortices, and should be further investigated.
