The first sanction applies to #contemptofparliament. The normal punishment for a non or former member is to be required to appear at the "bar of the house" (which, sad to say, is not a #hostelry !) to purge one contempt. In the effect of a failure to do so the individual in question will be arrested by the #serjeantatarms and detained in a cell under the #elisabethtower until they agree to purge their contempt. The sanction of detention has not needed to be used since the nineteenth century!
