Yes, it's still law. However, there's no time limit on the time the local authority might take to identify and/or lease a suitable site, and there may be some exemptions for some urban areas. My chum in Downham Market is trying to get the local authority to think ahead of the game in the light of the huge number of new houses being built in the town, where there are NO allotments. It's something that local authorities keep very quiet about, for obvious reasons.
