Portugal's Prime Minister Antonio Costa has resigned amid an investigation into alleged irregularities involving lithium mining and hydrogen projects. Infrastructure Minister Joao Galamba has been named as a formal suspect, and Costa's chief of staff has been detained. The opposition has called for the government to step down immediately. Costa stated that he is willing to cooperate with the justice system, but believes that the dignity of the prime minister's role is incompatible with any suspicion of criminal activity.
