Add the following as a new subrule to the rule entitled Parties, called Collective Responsibility:

Any time an Honourable Member who belongs to a Party loses Credibility, they may once, within 24 hours, Shift the Blame and increase their Credibility by the full amount so lost. They must then distribute the amount of Credibility that they would have lost as evenly as possible amongst all members of the same Party as themselves, with themselves losing any indivisible remainder. If there are more Honourable Members in the Party than Credibility to be distributed then all members of that Party except the Honourable Member whose Shifting of the Blame was the proximate cause of the Credibility loss lose 1 Credibility.

Honourable Members may transfer up to 5 Credibility to any other member of the same Party as themselves as a daily action.
