In each season, data are taken for one hour per night for roughly 60 nights during the six months that M31 is visible. The two 33x33arcmin^2^ fields of view straddle the central bulge, northwards and southwards. We have calculated the locations, periods and brightness of 35 414 variable stars in M31 as a by-product of the microlensing search. The variables are classified according to their period and brightness. Rough correspondences with classical types of variable star (such as Population I and II Cepheids, Miras and semiregular long-period variables) are established. The spatial distribution of Population I Cepheids is clearly associated with the spiral arms, while the central concentration of the Miras and long-period variables varies noticeably, the brighter and the shorter period Miras being much more centrally concentrated. Description: Observations of M31 were obtained using the Wide Field Camera (WFC) mounted on the 2.5-m Isaac Newton Telescope (INT) located at La Palma, the Canary Islands, Spain, over three observing seasons, from 1999 August to 2002 January. Three broad-band filters, g, r and i, were employed.
