Prime Minister of Singapore Lee Hsien Loong apologised to the nation yesterday for the harm caused by a protracted and publicly aired dispute with his siblings, which has affected Singapore's reputation and its citizens' confidence in the Government.

He will deliver a ministerial statement to refute the "baseless accusations" his siblings made against the Government, when Parliament sits on July 3.

Lee issued a statement and a video on the matter yesterday, on his first day back at work after a vacation. He expressed deep regret about the harm caused by the dispute with Dr Lee Wei Ling and Mr Lee Hsien Yang over whether to demolish their late father Lee Kuan Yew's house at 38, Oxley Road.

His siblings had released a statement last Wednesday accusing him of misusing his power in a bid to preserve their father's house, among numerous other allegations.
