Twenty-seven members of the Rivers State House of Assembly have defected from the Peoples Democratic Party (PDP) to the All Progressives Congress (APC).
A member of the Assembly, Enemi George, confirmed that the 27 lawmakers were under the leadership of Martin Amaewhule.
He said the decision was taken during their sitting on Monday morning.
For weeks, Amaewhule and another member, Edison Ehie, have been embroiled in a Speakership tussle. Amaewhule is believed to be loyal to ex-governor Nyesom Wike while Ehie is known to be in the camp of Governor Siminalayi Fubara.
The Assembly under Amaewhule had in October served an impeachment notice on the governor and removed Ehie as the House leader. However, some members of the Assembly loyal to Fubara immediately impeached Amaewhule and made Ehie the new Speaker.
