MANILA (Reuters) - Philippine Vice President Sara Duterte said on Friday she had been preparing since last year for impeachment and would welcome on her defence team her firebrand father, former President Rodrigo Duterte, if interested to join.

The Philippines' lower house has impeached Vice President Sara Duterte, the daughter of the country's firebrand former president, setting the stage for a rare, high-profile trial in the Senate.

A conviction would hamper the political ambitions of Sara Duterte, who has said that she would like to succeed President Ferdinand R. Marcos Jr.
