Fresh details have emerged on what led to the fallout between Deputy President Rigathi Gachagua and his boss William Ruto.

Gachagua is facing a genuine threat of impeachment, as more than 100 legislators are preparing to back a motion to oust him this week.

According to a report by NTV, a 40-page impeachment motion against Gachagua is ready for tabling and it reportedly contains nine damning allegations against the embattled deputy President.

Sharp differences between Gachagua and Ruto are believed to be at the centre of the motion, with the former reportedly banging the table in frustration after being denied a Ksh8 billion package by the President in one of their meetings.

Gachagua is said to have arrived at the figure by calculating every vote Ruto got in the Mount Kenya region by 4,000. The DP was reportedly only willing to walk away from his job if the sum was matched.

Furthermore, he is accused of abusing his office by diverting material meant to facilitate the construction of the Malindi-Kilifi Highway to a private road leading to a hotel linked to him.

The DP is also under scrutiny for allegedly accruing Ksh5.7 billion in his two years in office, which is a hefty amount compared to his annual salary of Ksh12 million.

Other charges likely to be tabled against the Gachagua include leaking state secrets despite taking an oath of secrecy, threatening and intimidating lawmakers, and allegedly sponsoring the violence that was witnessed by goons during the June and July Gen-Z protests.

Gachagua's 'one man, one vote, one shilling' narrative is also believed to be a huge promoter of tribalism, hence becoming a factor in his impeachment drive.

If the allegations against the Deputy President hold any weight, then by law, they are solid grounds to impeach him.

What the law says: As per Article 150(1)(b) of the Kenyan constitution, the impeachment of a Deputy President can be based on three grounds; gross violation of the constitution or any law, committing a crime under national or international law, and gross misconduct.

Amid a heavy onslaught against him, Gachagua is also unrelenting, and he made his stance clear during his latest public address on Saturday in Ngurubani town, Kirinyaga County.

"President Ruto should stop telling MPs to impeach me," he told the rally. "If he no longer needs Mt Kenya votes, he should inform us."

The embattled Gachagua was adamant he was elected alongside Ruto as he warned the President against undermining him.
