At least 53 out of 66 Senators voted Thursday evening to uphold charges levelled against him by the National Assembly last week.
"DP Gachagua ceases to hold office," Senate Speaker Amason Kingi said after the vote.
The vote came after a day of drama that saw the DP skip his cross-examination at the Senate after falling sick. The Senators held a vote to decide whether to continue with the impeachment process or adjourn to Saturday October 19. Eventually, most agreed that the process should continue in his absence, after which his battery of lawyers stormed out of the Senate in protest.

Ground 9, Gross misconduct that is incompatible with the high calling and dignified status of the Office of the Deputy President and a member of the Cabinet and the National Security Council. H. E. the Deputy President has publicly attacked and undermined the work of the National Security Intelligence Service and its Officers), 46 voted YES and 20 voted NO, while 1 abstained.
With the Senate confirming his impeachment, the DP's battle will likely to move to courts which could reinstate him in office - if he establishes sufficient grounds - until determination of the petition.
The besieged DP has consistently expressed confidence in the Judiciary signaling he is prepared to fight all the way to the Supreme Court, a protracted legal battle that could even drag on to the end of their term with President Ruto.
Barring any court orders in the coming days, the impeachment paves way for the nomination and subsequent approval of a replacement by his former boss William Ruto.
