The Scottish National Party (SNP) has pledged to scrap the Trident nuclear weapons system, branding it a "colossal waste of money".
The SNP has launched its manifesto ahead of the General Election on Thursday 12 December.
During the launch in Glasgow, SNP leader Nicola Sturgeon said: "It's been estimated that the renewal of the Trident nuclear weapons system could cost more than £200 billion.
"That is a colossal waste of money and weapons of mass destruction are immoral."
Ms Sturgeon added: "A key SNP demand for our support will be for the removal of Trident from Scotland and the saving of billions of pounds to be invested instead in our precious public services."
The SNP also wants the building of the Royal Fleet Auxilary's Fleet Solid Support Ships to be restricted to UK shipyards.
It also wants to give Commonwealth troops, and their families, the right to remain in the UK after their service, as well as using vacant Ministry of Defence (MOD) homes to house homeless veterans.
The manifesto states: "SNP MPs will continue to challenge the UK government over its record and pressure the government to tackle homelessness by committing to a key SNP pledge that the Ministry of Defence use vacant MOD homes to house homeless ex-servicemen and to ensure that Commonwealth personnel in the UK armed forces and their families to receive indefinite right to remain during and after service in the UK military."
