We present the results of a set of numerical simulations aimed at studyingreionization at galactic scale. We use a high resolution simulation of theformation of the Milky Way-M31 system to simulate the reionization of the localgroup. The reionization calculation was performed with the post-processingradiative transfer code ATON and the underlying cosmological simulation wasperformed as part of the CLUES project. We vary the source models to bracketthe range of source properties used in the literature. We investigate thestructure and propagation of the galatic ionization fronts by a visualexamination of our reionization maps. Within the progenitors we find thatreionization is patchy, and proceeds locally inside out. The process becomespatchier with decreasing source photon output. It is generally dominated by onemajor HII region and 1-4 additional isolated smaller bubbles, which eventuallyoverlap. Higher emissivity results in faster and earlier local reionization. Inall models, the reionization of the Milky Way and M31 are similar in duration,i.e. between 203 Myr and 22 Myr depending on the source model, placing theirzreion between 8.4 and 13.7. In all models except the most extreme, the MW andM31 progenitors reionize internally, ignoring each other, despite beingrelatively close to each other even during the epoch of reionization. Only inthe case of strong supernova feedback suppressing star formation in haloes lessmassive than 10^9 M_sun, and using our highest emissivity, we find that the MWis reionized by M31.
