In an attempt to mount pressure on the Government, MPs of DMK, a major partner of the ruling UPA, today attended House proceedings wearing black shirts after staging a protest inside the Parliament House complex.
Expressing solidarity with agitating members, DMK representative in the Government, Minister of State for Finance S S Palanimackam also wore a black shirt though he did not participate in the protest.
Speaker Meira Kumar may allow a short duration discussion on the Sri Lankan Tamil issue on Thursday under Rule 193, which doesn't entail voting, sources said.
Outside Parliament, DMK MPs staged a protest carrying placards which read 'Save Tamils in Sri Lanka'.
