Former speaker yakubu dogara reveals why he dumped pdp

I think there may be some confusion here. Yakubu Dogara is a former Speaker of the House of Representatives in Nigeria, but I couldn't find any credible sources indicating that he has dumped the People's Democratic Party (PDP).

In fact, Dogara is still a member of the PDP and has been vocal about his support for the party. It's possible that you may be thinking of another politician who has defected from the PDP.

If you could provide more context or clarify what you're referring to, I'd be happy to help you find the information you're looking for.
