A Federal High Court in Abuja has sacked Yakubu from the House of Representatives and declared his seat vacant.
Mr Dogara, who represents Bogoro/Dass Federal constituency of Bauchi State, was the Speaker of the House of Representatives between 2015 and 2019.
Mr Dogara defected to the APC after winning his re-election under the PDP in 2019
His frosty relationship with his state governor, Bala Mohammed, was one of the main reasons he ditched the PDP which he joined less than five years ago.
Mr Dogara had on July 24, 2020 dumped the PDP and returned to his former party, the APC.
Mr Dogara had earlier in 2018 dumped the ruling party for the main opposition platform after having political confrontation for about two years with the then governor of Bauchi State, Mohammed Abubakar.
In a letter of resignation addressed to the Bogoro ‘C’ Ward Chairman of the PDP dated July 24, 2020, Mr Dogara cited a breakdown of governance in his native state of Bauchi under the administration of Governor Bala Mohammed whom he said he helped installed as a governor in 2019.
