The Green Party will launch a "Pledge against Racism" campaign during a conference at Trinity College Dublin today.
The pledge, which the party wants politicians and community leaders to sign, would provide for the removal from office or suspension of those who make racist remarks or condone racist actions of others.
The Taoiseach has appointed TDs who have made "fairly dangerous remarks" about immigrants to chairmen of Dáil committees, Mr Ciarán Cuffe, the Green Party's justice spokesman, said.
Mr Cuffe said Mr Ivor Callely, a junior minister at the Department of Health and Children, has said the Government should "get tough" on asylum seekers. Mr Noel O'Flynn, the new chairman of the Dáil Committee on Communications and Natural Resources, has accused some asylum seekers as being "spongers and freeloaders".
"These remarks simply fuel the fires of racism," Mr Cuffe said.
