When you last raised this, Stephane Bortzmeyer pointed out that the
delegation of lkl.ac.uk was fubar'ed. It still is.

The authoritative ac.uk nameservers believe that the nameservers for
lkl.ac.uk are

  ns1.lonklab.ac.uk
  mail1.ccs.bbk.ac.uk

The first has a plausible copy of the zone, but the NS records in it
bear no relation to those above. The second doesn't know anything about
the zone, so this appears as a "lame delegation".

Until you get this fixed, you are going to have unpredictable results
depending on the order nameservers are queried.
