The Conservatives are releasing a poster warning against SNP influence over Labour.
Tories are pushing the Prime Minister to consider how he could work with Salmond's party in a hung parliament.
A more social democratic Britain can be achieved, and Scottish Labour's recovery set in train, if a deal is done between Labour and the SNP.
In the event of a hung parliament, the former First Minister is likely to be the SNP MP to do the deals.
Having concededed that a Labour government is superior to a Conservative one, the SNP will need to explain why it is working to prevent one.
The former first minister is expected to announce that he will stand for the Gordon seat held by retiring Lib Dem MP Sir Malcolm Bruce.
The natural next step for Scotland's outgoing First Minister would be a return to Westminster.
