TDs who have resigned on principle or in controversy
* FIANNA Fail TD Dr Jim McDaid resigned his seat in Donegal North East on November 2, 2010, citing personal reasons.
He also criticised the FF-led government for failing to make significant progress on deficit reduction. His resignation letter stated: "Our primary focus has been on the survival of government instead of the health of the economy."
* George Lee resigned his Fine Gael seat in 2010, because he felt he was not having any input into the party's economic policies.
Enda Kenny offered him the position of spokesman on economic planning but Lee said it would have been dishonest of him to accept the position as he "had absolutely no input for nine months". He returned to RTE in May 2010.
* Ray Burke was appointed Minister for Foreign Affairs by Bertie Ahern in 1997. Within months, allegations of corruption against Burke resurfaced. The Fianna Fail TD resigned from the Cabinet and from the Dail on October 7, 1997, just four months into the job.
The Flood Tribunal detailed how Burke had received corrupt payments from businessmen.
In 2004, he pleaded guilty to two charges of making false tax returns.
He was sentenced to six months in prison for the offences and served a four-and-a-half-month term.
* Fianna Fail TD Kevin Boland resigned from government during the arms crisis in 1970 in sympathy with dismissed ministers Neil Blaney and Charles Haughey.
Boland attacked Lynch over the sackings. He refused to vote with Fianna Fail when Fine Gael challenged the government and resigned his seat.
* Dublin South Central TD John 'Jack' Murphy, the first unemployed person elected to the Dail, gave up his seat in May 1958.
The Independent deputy, and member of the Unemployed Protest Committee, resigned just over a year after he had been elected. Murphy's aim had been to put pressure on the government on behalf of the unemployed but he stepped down in frustration after being unable to make any progress.
