Tanaiste takes swipe at Gerry Adams at Labour conference
Ms Burton also hit out at Fianna Fáil, accusing the party of "creating the monster that was the bank guarantee".
In her opening address, Ms Burton listed off several measures achieved by Labour in government.
These include the landmark X case legislation, protecting the old age pension and a planned €4bn social housing investment programme.
But Ms Burton admitted that her party faces a "tough" battle if it wants to serve in a second consecutive government term.
"It’s going to be tough. But it’s a fight we embark upon with utmost conviction," she told delegates.
In relation to the bank guarantee, Ms Burton turned on the Opposition.
"Fianna Fail created the monster that was the bank guarantee – and Sinn Fein voted for it," she said.
"Unlike Gerry Adams, I’m good at figures. I knew the bank guarantee was a bust," she added.
The three day conference will see debates take place on issues such as abortion, same sex marriage and Aer Lingus.
SIPTU President Jack O"Connor will tomorrow address a fringe group within the party which is calling for Labour to cut ties with Fine Gael after the next election.
