We present results from Interplanetary Scintillation (IPS)observations made jointly with the EISCAT system in Scandinavia and the MERLIN system in the UK. These results provide evidence of a small but measureable equatorwards velocity component in the fast solar wind typically of the order of 1° - 2° off radial direction. Possible reasons for this expansion and further investigations are discussed.
