A member can miss a division for many reasons: illness, leave, ministerial duties, being in the chair or a pair arrangement. "Against their party" means at least three quarters of the rest of their party voted the other way; votes where any party split (usually free or conscience votes) don't count. Votes on procedure aren't listed.
