The first VLBI image of the powerful radio galaxy PKS 2152-699 has been presented. This image shows that the pc-scale radio jet is aligned closely with the ENELR, but not the kpc-scale radio lobe to the north-east of the radio/optical core. These results favour the interpretation of Tadhunter et al. [1988], who suggest that the radio jet from the core could be interacting with an extra-nuclear cloud of gas, causing the radio jet to be deflected in the process. A mechanism, consistent with this interpretation, which can reproduce the observed misalignment between the kpc-scale radio structure and the ENELR has been explored. The resultant model uses oblique shocks and a relativistic jet to produce the observed (projected) 20
jet deflection. The excitation of the ENELR could be due to both the jet/cloud interaction and the effects of a photon beam from the nucleus.
