Dr Lee and Mr Lee Hsien Yang release a Facebook statement saying they have lost confidence in PM Lee and fear the use of state organs against them, citing a ministerial committee set up to consider options for their late father's house. "We privately offered a ceasefire shortly after our statement of June 14, 2017. Our attempts at reconciliation were rebuffed," say Dr Lee and Mr Lee Hsien Yang.

Accusations and rebuttals are traded over the issue. In the course of things, PM Lee brings up his misgivings over the circumstances surrounding the last will of their father.
PM Lee apologises to Singaporeans for the harm caused by the very public and protracted dispute, and says he will make a ministerial statement in Parliament to answer to the allegations.

Parliament debates the allegations over the abuse of power, with PM Lee and other ministers delivering statements to rebut the accusations.
At the end of the debate, PM Lee says his siblings' "allegations have been aired, have been answered and rebutted", and there is no evidence that he or the Government has abused their power. He also says he hopes to reconcile with his siblings one day.
Dr Lee and Mr Lee Hsien Yang say "it is impossible for MPs to effectively question PM Lee, when his party controls almost all the seats in the House", despite the People's Action Party having lifted its Whip.

Dr Lee and Mr Lee Hsien Yang welcome PM Lee's gesture to settle their quarrel in private.
They add in their statement that they will not post any further evidence on social media as it will only muddy the facts. This is "provided that we and our father's wish are not attacked or misrepresented".
They also apologised to Singaporeans, saying: "We have made a lot of mistakes along the way; please forgive us."
