What we do have is typically called a “program for government”. When there's a coalition, the coalition parties will get together and agree on a program for government. That tends to have to go back to the party conference of each party to approve going into coalition with that program from the members. In that way there is some external validation for it, but once they've gone in, that's the program they try to deliver.
