Purdah (pre-election period)

Purdah () is the period in the United Kingdom between the announcement of an election and the formation of the new elected government. It affects civil servants, who must be politically impartial, preventing central and local government from making announcements about any new or controversial government initiatives that could be seen to be advantageous to any candidates or parties in the forthcoming election.
