Kathumba became the independent MP for Lilongwe Mapuyu South in 2019[1] when she defeated the sitting member.
[2] In April 2020 she and fellow Lilongwe MP Monica Chang'anamuno went to court over the legality of the measures brought in by the President to deal with the COVID-19 pandemic because they were not constitutional.
Kathumba argued that the President's decaration of a State of National Disaster in March and the announcement by the Minister of Health of a three week lockdown (a few days before) was unconstitutional.
[3] In 2024 she proposed that parliament should change the law to allow President Chakwera to exceed the two-term maximum service and that he should be made President-for-life.
The Malawi Congress Party were swift to disown the proposal which one commentator called immature.
