Kenya's High Court began Tuesday hearing an appeal by impeached Deputy President Rigathi Gachagua over his ouster in an unprecedented Senate vote last week.

But as the proceedings got under way, President William Ruto filed an objection, saying the court did not have the jurisdiction to hear the case and that it was a matter for the Supreme Court.

The High Court in Nairobi had on Friday ordered the historic impeachment to be put on hold. It came just minutes after parliament had approved Interior Minister Kithure Kindiki to replace Gachagua as Ruto's deputy.

Gachagua, who was in court for Tuesday's hearing, was impeached by the Senate on Thursday on five out of 11 charges against him, including stirring ethnic divisions and undermining the judiciary.

'Unfair process'

The 59-year-old has denied all the allegations, and his legal team had swiftly launched an appeal alleging the process had been unfair and rushed.

"The petition and application raise monumental constitutional issues," the High Court said in its ruling on Friday that blocked Kindiki from taking office.

The impeachment - the first time in Kenya that a deputy president has been removed from office in this manner - is the culmination of a public falling out between Gachagua and Ruto.

Gachagua had been admitted to hospital with chest pains shortly before he was due to testify before the Senate, but the upper house rejected an appeal by his lawyers for the process to be delayed.

Attempts on his life

After being discharged, Gachagua on Sunday lashed out at his boss as "vicious" and claimed there had been attempts on his life in the past, including by poisoning his food.

The powerful multi-millionaire businessman, known as "Riggy G", also said his security had been withdrawn and his entire staff sent on compulsory leave.

Ruto - who had chosen Gachagua as his running mate for the August 2022 election - has not yet given any public comment on the impeachment.

Gachagua had helped Ruto to victory in the closely fought election race against veteran opposition leader Raila Odinga by rallying support from the crucial Mount Kenya region.

'Vicious president'

"I am shocked by how vicious a man I helped to be president, believed in and was persecuted when I supported, could be so vicious against me," Gachagua told reporters on Sunday.

"If anything happens to me or my family, President William Ruto must be held to account," he said.

The Directorate of Criminal Investigations on Monday had asked Gachagua to make a statement to police about what it described as "serious allegations" about attempts on his life.
