N2 - Using the pseudo-Newtonian (RN) potential reflecting properties of the Schwarzschild-de Sitter spacetime, we estimate the influence of the repulsive cosmological constant Lambda similar to 1.3 x 10(-56)cm(-2) implied by recent cosmological tests onto themotion of both Small and Large Magellanic Clouds (SMC and LMC) in the gravitational field of the Milky Way. Considering detailed modelling of the gravitational field of the Galaxy disc, bulge and cold dark matter halo, the trajectories of SMC and LMC constructed for the PN potential with the cosmological constant are confronted to those given for Lambda = 0. In the realistic model of the extended cold dark matter halo its edge and related total mass are taken at typical values reflecting recent diversity in the total Galaxy mass estimates. In all cases, strong influence of the cosmological constant, on 10% level or higher, has been found for motion of both SMC and LMC. Inside the halo, the Newtonian part of the PN potential is exact en
