Romanian prosecutors have asked Parliament to lift the immunity of a former tourism minister, once one of the country's most influential politicians, so she can be arrested on suspicion of bribery and money laundering.

The anti-corruption prosecutors' office wants to arrest Elena Udrea, a close aide of former President Traian Basescu, who was in office from 2004 to 2014.

The prosecutors' statement on Tuesday said Udrea, who also wielded influence in the economy ministry, received $3.8 million in 2012 from a businessman in the energy sector in exchange for allowing him to control an electricity provider. Prosecutors said she is also suspected of making false statements, influence peddling and abusing her position.

Udrea, the tourism and regional development minister from 2008 to 2012, denies wrongdoing.
