Bomet Member of Parliament Beatrice Kones on Wednesday decamped from the Orange Democratic Movement (ODM) to Eldoret North MP William Ruto's United Republican Party (URP).
Speaking when he officially received her at the party headquarters, Ruto said URP will hold a welcome rally in Bomet next Friday to welcome her officially, together with her supporters.
"We welcome her to the winning party, the party that will form the next government," he enthused.
During the welcome session, Ruto asked the government to mobilise all security resources including personnel to deal with the ongoing conflict in various parts of the country. Ruto regretted that insecurity has risen to unacceptable levels.
"Authorities responsible should up their game, roll up their sleeves, tighten their belts, pull up their socks and get on to mobilise every resource available - hardware and software - and deal with the security situation in the country," he asserted.
He asked the government to take immediate action to save innocent Kenyans from dying in the hands of criminals.
He also expressed fears that even security officers who are supposed to protect others were also suffering in the hands of killers unleashing all sorts of violence and revenge.
"When people attack citizens - that is criminal, when criminals kill security officers, that is a declaration of war," Ruto said.
Ruto also warned criminals involved in killings and violence that the law will catch up with them.
"We must send a clear message to crooks, rustlers and criminals that business is closed down. If they want to continue they must look for another business, either sell charcoal, or sell stones in a quarry; it is not accepted that crooks can continue to roam in our country," he said.
Forty eight police officers were recently massacred in Baragoi, Samburu County by cattle rustlers who ambushed the security officers as they proceeded on an operation to recover stolen livestock.
There have been similar incidences in Tana and parts of North Eastern Kenya. This week the country woke up to new violence in Eastleigh linked to xenophobic attacks.
Killings and attacks linked to terrorism have become almost a weekend ritual in Kenyan churches, roads and other public places.
