US President Joe Biden and former President Donald Trump prepare to go head to head in televised debates.

Also on the programme: more protests in Kenya even after the President U-Turns on his controversial tax policy; a BBC investigation tracks down a prolific people smuggler involved in trafficking people across the English Channel; and new research warns that AI-generated essays score higher grades than student-written scripts and are virtually impossible for universities to detect.
