... then CCHQ does have the right to impose candidates on constituencies who have not yet chosen. As much as local associations may wish to retain their independence, this is one instance in which they really have no choice.
Dozens of associations have yet to selected their candidates – including some in key marginal seats which the Conservatives have to win to deprive Labour of an overall majority, such as Rochester in Kent.
Local associations jealously guard their independence and will resist any move by Conservative Central Office to impose candidates from Mr Cameron's A-list which was devised to help more women, ethnic minority, and gay candidates secure winnable seats. (The Telegraph)
This does not need to be a long-term commitment for either candidate or association. It could be simply for the duration of this campaign - so long as they don't win, of course [which is unlikely considering that nearly all of the target seats have already been selected for]. The A-list are the perfect people for this role - even if it no more than just putting bums on seats. They are presumably some of the best candidates that the party has to offer. For both it also could well prove beneficial, allowing them to see each other in real action before a real selection.
As much as the associations are right to guard their local independence from central interference, in the case of a snap election, it is the role of the central party to organise and respond to these things. Unless an association is willing to agree on a short-term potential candidate until the threat of a snap election is either gone or actualised, this is the only alternative. And on the side of CCHQ, it must be made clear that any imposition of candidates is only for the duration of the campaign and election, after which it is back to "business as normal," with associations again able to select their own candidates. Independence is all well and good, but it is the greater good of the party as a whole that must come first in these situations.
