Some 1,000 citizens have already assembled in front of Parliament in Bulgarian capital Sofia Thursday to support PM Boyko Borisov while the House debates his resignation.
A man has even driven in a truck carrying piglets to express the support of agriculture producers for the cabinet.
Other agriculture producers have arrived with tractors.
Citizens from different towns across the country have been driven in with buses, report agencies.
Protesters started to assemble as early as 8 am EET, their numbers gradually swelling.
They are shouting the name of PM Borisov, and slogans such as "Boyko, do not leave us!"
Borisov said the cabinet is stepping down Wednesday morning, after protests that had gripped the country failed to abate following a major cabinet reshuffle, and even turned violent.
Some citizens reacted by speaking out against the resignation and showing support for Borisov and his cabinet.
A Facebook page made Wednesday morning following the resignation, has now gathered more than 34,000 'likes'.
Petitions have been started to show the support for the cabinet.
At the same time, it was reported Wednesday that ruling GERB party functionnaires mailed supporters - and civil servants - suggesting they come out for the pro-Borisov rallies.
