Matawalle worked as a teacher at Government Girls College, Moriki and Kwatarkoshi before joining the Federal Ministry of Water Resources. Matawalle's first shot in politics was in 1998 when he ran for a house of assembly seat and won after he left the Federal Ministry of Water Resources, Abuja, joining the defunct United Nigeria Congress Party (UNCP) which consisted of politicians such as Ambassador Isa Aliyu Mohammed Argungu (Sarkin Yakin Kabbi) former Minister of Water Resources and National Chairman of the party, Ibrahim Gusau former pro tem National Chairman of the party, Atiku Abubakar, Abdullahi Aliyu Sumaila, Attahiru Bafarawa, Adamu Aliero, Suleiman Takuma, Ibrahim Kura Mohammed, Ibrahim Saminu Turaki and Kabiru Ibrahim Gaya but after the death of Sani Abacha, Nigerian Military Head of State on 8 June 1998, Abdulsalami Abubakar, his successor, dissolved the political parties and announced that elections would hold in 1999.
Between 1999 and 2003 he served as Zamfara State Commissioner for Local Government and Chieftaincy Affairs, Commissioner for Environment, Rural Development and then Commissioner for Youth and Sports.
Matawalle was elected into the House of Representatives by his constituents Bakura/Maradun in May 2003 on the platform of the defunct All Nigeria Peoples Party (ANPP).
Matawalle was re-elected in 2007 still on the platform of the ANPP only to defect to PDP on which platform he was re-elected for a third term in 2011.
Matawalle polled 189,452 in the March polls as against the 534,541 votes for Muktar Idris, the APC candidate.
Muktar Idris was at first, issued the certificate of return, however, the court of appeal in Sokoto ordered that the INEC should withdraw the certificate.[4]
The Supreme Court later pronounced that the votes cast for the APC in the election as wasted and ordered that the candidate with the second highest votes be sworn in on Wednesday. This is because the APC failed to conduct primary election for all the candidates in Zamfara State.[5]
Defection to APC
On 1 June 2021, Matawalle dissolved his Executive Council, reportedly in preparation for a party switch to the APC set to happen around June 12.[6] Matawalle however, denied that the cabinet dissolution was connected to a party switch and claimed to have not made a decision on changing parties nor set a date.[7]
On 27 June, President Muhammadu Buhari's Personal Media aide Bashir Ahmad said Matawalle had joined the APC. The party switch was later confirmed by Matawalle's spokesperson Ibrahim Dosara, who said Matawalle would formally announce the defection on June 29.[8] On June 29, Matawalle, along with all 3 Zamfara Senators, 6 of 7 Representatives, and all 24 House of Assembly members, officially switched to the APC at a rally in Gusau attended by other APC Governors; notably Deputy Governor Mahdi Mohammed Gusau and Anka/Mafara Representative Kabiru Yahaya remained in the PDP. Mai Mala Buni, Yobe State Governor and APC Caretaker Chairman, immediately dissolved all party caretaker committees in Zamfara State and appointed Matawalle as Zamfara APC Leader.[9]
