I was elected under the able leadership of President Nelson Chamisa who I wholeheartedly believe will deliver this country to the land of milk and honey that we beseech. I remain and stand by President Nelson Chamisa.
Marondera Central; our very voice that you proclaimed in 2018 has been beaten BUT it will never be silenced. In the two years, I have had a lot happen to me including the merciless shooting at my house. I have never shaken and I will continue to be that voice. They may remove me from the Parliament building but they can never remove me from the hearts and people of Marondera.
Cdes and friends, we live to fight another day.

Allegations against Mwonzora
I was offered many positions in the MDC-T, but I said no I will not betray my president, Nelson Chamisa.
The car was taken away from me. I lost all the Parliament benefits and salaries but at the end of the day it’s not about me but the people of Marondera who need representation.
You have got (Emmerson) Mnangagwa and Mwonzora in bed together, they are working hand in glove.
In May 2022, Matewu was involved in a road accident when he lost control of the vehicle, a Toyota Fortuner, which veered off the road before hitting a tree.
Initial reports suggested that he was on COVID-19 business but it later emerged he was coming from a party with six passengers aboard the vehicle.
Matewu claimed that he was involved in the accident after he tried to avoid colliding with a speeding “unmarked vehicle” that was moving toward him. .
He was asked to withdraw his remarks but he declined to withdraw arguing that his remarks were not wrong. .
