“He will also use his stay in the UK to rest and relax, which he doesn’t do enough back at home,” Onyango said.
The Azimio boss separately confirmed the visit in a social media post on Saturday.
In the post, the former prime minister said he bumped into US Senator Chris Coons while en route to the UK. The Delaware senator was heading home after his recent visit to the country, where he held separate meetings with the Azimio leader and President William Ruto.
“Our paths crossed again last night with my friend Senator Chris Coons heading home to the US while I left for the UK. Wished each other safe flights, hoping to see each other again. Always a pleasure Chris,” Raila wrote on Facebook.
