The Director of Public Prosecutions (DPP) has urged a Kenyan court to extradite Brian Kiprop Kiplagat to the United Kingdom to face charges, including the alleged murder of his girlfriend, Marianne Kilonzi, in London in January 2025.
Senior Assistant Director of Public Prosecutions Duncan Ondimu, who is leading the prosecution, told the court that Kiplagat is wanted by British authorities over alleged offences committed in Woolwich, within the London Borough of Greenwich, between January 12 and 28, 2025.
The prosecution opposed attempts by the defence to introduce evidence challenging aspects of the extradition request, arguing that the proceedings were not intended to determine Kiplagat’s guilt or innocence.
Ondimu maintained that the Kenyan court’s role was to establish whether the legal requirements for extradition had been met, paving the way for the allegations to be heard by the courts in the United Kingdom.
According to the prosecution, the Westminster Magistrates’ Court issued warrants against Kiplagat in connection with eight counts: murder, manslaughter, two counts of perverting the course of justice and four counts of fraud by false representation.
The charges relating to obstruction of justice concern allegations that Kiplagat placed laundry beads on Kilonzi and removed her mobile phone from her residence. The fraud allegations involve claims that money was transferred from Kilonzi’s bank accounts into accounts held by Kiplagat without authorisation, alongside the alleged unlawful use of her credit card.
The extradition documents state that Kiplagat and Kilonzi began their relationship in January 2024 after meeting on WhatsApp. By September of the same year, he had reportedly moved into her residence.
The latest proceedings follow earlier steps by Kenyan authorities to facilitate his potential transfer to the UK. In June 2026, the DPP approved the commencement of extradition proceedings after receiving a formal request from British authorities.
A Nairobi court subsequently allowed the recognition and enforcement of arrest warrants issued in the UK, enabling the process to advance under Kenyan law.
The prosecution has also assured the court that Kiplagat’s constitutional rights would be protected throughout the proceedings, including his access to healthcare. It further stated that property unrelated to the extradition case would be returned to him.
The DPP argued that extradition would allow the allegations to be addressed through the appropriate judicial process in the UK while ensuring compliance with the law and safeguarding the suspect’s rights.
The matter will be mentioned on November 5, 2026, with a ruling scheduled for November 19, when the court is expected to determine the next step in the extradition proceedings.
