A Blocking Motion may be put down against a Private Bill by one or more backbench MPs. It is an attempt to prolong discussion of an issue and if passed means that time has to be found at a later date to debate the bill at length. Notice of a blocking motion must be given which must appear on the order paper together with the names of the members concerned. Private bills are normally taken after prayers on Mondays to Thursdays, and often go through `on the nod', or without debate.
