Prior to resigning, John Tucker stated support of Jeremy Rockliff

The Lyons MHA made his comments in Parliament on March 22, where he expressed his support of the stadium project.

"Premier Jeremy Rockliff leads a government that is committed to supporting all Tasmanians, he deserves our loyalty and respect."

On Sunday afternoon, Mr Tucker claimed that he and Mr Rockliff discussed his resignation a little more than a week later, but they resolved to address it upon his return from a stint of leave.

Along with a resignation from Bass MHA Lara Alexander, Tucker's move threw the Tasmanian Liberal government into minority last Friday.

In a joint statement the pair said "the proposed AFL stadium in Hobart was the trigger issue for us; however, it is much more than that. The stadium plan is the most obvious example of a government, which has lost its way."

Mr Tucker said his current position was that the whole stadium deal must be subject to better scrutiny, must take growing public concern into consideration through exhaustive consultation and for the government to be fully accountable to all Tasmanians for the decisions they made.

"Any [previous] comment that appears at odds with this very clear position must be viewed through the context of wearing a Liberal Party hat, which no longer applies," he said.

"I first raised my concerns about the proposed stadium with the Premier shortly after he assumed office.

"I specifically informed the premier that I was not receiving any positive feedback or support from Lyons voters."

Ms Alexander said earlier on Sunday that the large protest against the proposed stadium had vindicated her decision to resign from the Liberals.

In January, Mr Tucker said on social media, that major infrastructure leading to a bigger economy and more money for schools, hospitals, and roads was "common sense thinking."
