Kirkilas believes that this could persuade the LSDP not to withdraw from the ruling coalition with the LFGU.
The vice-chairman came up with the idea of such a memorandum in the run-up to next month's meeting of the LSDP council which is expected to decide whether or not to pull out from the government coalition.
In making its decision, the council will take into consideration of the opinion of the party's branches. The majority of the branches that have already stated their position are in favor of leaving.
"It's just an idea at the moment, but it's an attempt to make the relations within the coalition more formalized and to propose socially-orientated program package," Kirkilas told BNS on Thursday.

There are also five non-attached parliamentarians.
