Wiper leader Kalonzo Musyoka on Tuesday ate a humble pie and appeared before the Azimio running mate selection panel.
The former Vice President vacated his earlier threat to snub the grilling team and presented himself for the exercise on Tuesday.
Kalonzo arrived at Serena, the venue of interviews at exactly 9.14 am.
He was ushered into the interview room where the seven-member panel is administering oral questions by the panel's Secretary Elizabeth Meyo and Committee's legal advisor Paul Mwangi.
Kalonzo's change of heart comes a day after Kanu chairman Gideon Moi withdrew from the interviews and declared support for the Wiper party boss.
The panel's line of questions includes; one's political experience, professional qualifications and general questions on how to tackle pressing national challenges like corruption and youth unemployment.
Former Gatanga MP Peter Kenneth will be the second nominee to face the panel on day two of the interviews.
The Committee is expected to conclude the interviews today and submit three names to Raila before midnight.
Also to face the panel are Kitui Governor Charity Ngilu, former MP Stephen Tarus and Agriculture Cabinet Secretary Peter Munya.
