There's never assured positions, it may be a reshuffle would be done by Corbyn.
There is speculation Mrs May will be doing one,possibly even moving the Chancellor too who has been markedly absent near all through this campaign.

I doubt Abbott would be Home Secretary actually,I'm not that sure she even would mind not being so.
In light of the terrorist attacks,Corbyn and other Parties are re assessing plans.

It's like all Parties saying no deals if there's a hung parliament.
There'd have to be to govern.

However elections throw up odd situations, I think it more likely than not that Abbott would not be Home Secretary.
