The Liberal Democrat conference will host a debate on whether to break up the Royal Bank of Scotland into local and community banks.
Its autumn conference agenda, Fairer Tax in Tough Times, sets out policy debates that will be held when the party meets on 22-26 September.
Along with the debate on RBS, the Lib Dems will also consider whether to give the FCA a statutory responsibility to encourage banking competition.
Members will vote on whether to uphold the proposals as part of a debate on the Lib Dem sustainable prosperity and jobs policy paper which is being backed by MP Duncan Hames.
The Lib Dems also lament the lack of a housing policy from successive governments and will debate the housing policy paper, Decent Homes for All.
The agenda proposes stimulating a major programme of house building and increasing the rate of construction until it reaches more than 300,000 houses a year.
It suggests using untapped sources of finance and giving more freedom to social landlords, local authorities and local communities.
The coalition partner also wants to see radical steps to improve land supply, through releasing public land with “build now, pay later” deals.
And it calls on the Government to tackle landbanking through Community Land Auctions, “use it or lose it” planning permissions and a competition review of the major builders.
