Lawan declares bayelsa govs seat deputy vacant

I think there may be a small mistake in your question. Lawan is the President of the Senate, not the Governor of Bayelsa State. Therefore, it is unlikely that he would declare the seat of the Governor of Bayelsa State vacant.

However, if you meant to ask about the Speaker of the House of Representatives, Femi Gbajabiamila, declaring the seat of the Deputy Governor of Bayelsa State vacant, I would need more information to provide a accurate answer.

Could you please provide more context or clarify which Lawan you are referring to?
