Akaev says that putting his emotions aside, he thinks Bakiev and Kulov provide the best solution for the challenges facing Kyrgyzstan.
He says those challenges include strengthening political stability and developing democracy.
Kulov and Bakiev have agreed on a tandem -- if Bakiev wins the 10 July vote, Kulov will be his prime minister.
Kulov, imprisoned during part of Akaev's rule, dropped out of the race as part of the deal.
