The investigation centers around allegations of misconduct related to the award of concessions for lithium mining and hydrogen projects in the country. Police arrested Vitor Escaria, Chief of Staff to Prime Minister Antonio Costa, and five others. The state prosecutor's office stated that the Supreme Court will examine the "use of the prime minister's name and his involvement" in order to uncover the activities under scrutiny.

Infrastructure Minister, Joao Galamba, was also formally identified as a suspect by prosecutors. Arrest warrants have been issued for the mayor of the town of Sines, where some of the projects were slated to take place, as well as for two executives from the Start Campus company, responsible for the construction of the hydrogen production project and data centre.
