The SNP has appointed Angus Robertson MP to run the party's 2015 general election campaign.
Mr Robertson, who is MP for Moray and SNP Westminster group leader, directed the the party's successful 2007 and 2011 Holyrood campaigns.
Deputy leader Dundee East MP Stewart Hosie will be responsible for producing the manifesto.
SNP leader and First Minister Nicola Sturgeon said both men had "substantial records of electoral success".
She said: "It is increasingly likely that next year's general election will result in a hung parliament, and it is therefore vital that Scotland returns more SNP MPs to help deliver a progressive policy agenda at Westminster.
"We have the strongest levels of support we have ever had going into a UK election - following our extraordinary membership and polling boost since the referendum - but we take nothing for granted."
Mr Robertson said: "We have great opportunities at the general election to advance Scotland's interests - the more votes and seats the SNP win, the more the Westminster establishment will have to pay attention to what people in Scotland want."
Mr Hosie added: "The SNP policy agenda will reflect the aspirations of the people of Scotland - an end to failed austerity economics, policies to boost growth, jobs and social justice, cancellation of the ludicrous plans to renew Trident nuclear weapons at a cost of £100 billion, and securing the powers Scotland's Parliament needs to build prosperity and a fairer society."
