Recently, there have been shown that in planar liquid crystalline waveguides light beams can form spatial soliton due to the reorientational nonlinearity. Such self-trapped beams require only a few tens of mW of light power and their stability is controlled, by the state of light polarisation. In this paper, the collision of previously observed solitons are analysedd theoretically. Obtained results show that analysed self-trapped beams became unstable due to interaction with otheir light beams.
