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.

Young lawmakers from the House of Representatives have claimed that Vice President Sara Duterte’s seemingly cool demeanor while discussing her impeachment is just a facade as her statements only reinforce the belief that she is anxious over the issue.
