No excess of bright galaxies around the redshift 7.1 quasar ULAS
  J1120+0641
  We present optical and near-infrared imaging of the field of the z=7.0842
quasar ULAS J112001.48+064124.3 taken with the Hubble Space Telescope. We use
these data to search for galaxies that may be physically associated with the
quasar, using the Lyman break technique, and find three such objects, although
the detection of one in Spitzer Space Telescope imaging strongly suggests it
lies at z~2. This is consistent with the field luminosity function and
indicates that there is no excess of >L* galaxies within 1 Mpc of the quasar. A
detection of the quasar shortward of the Ly-alpha line is consistent with the
previously observed evolution of the intergalactic medium at z>5.5.
