Khembo was elected in 2014 to the, now superseded, constituency of Neno South Constituency as a member of the Democratic Progressive Party and she served until 2019.[1]
She was elected to parliament in the 2025 election in September at the same time as Mutani Tambala[2] also became a Democratic Progressive Party MP. Khembo was elected in Neno East and Tambala in Neno South. Activists who had been trying to encourage women candidates held Neno up as "Malawi’s top performer in women’s political representation" as they also had Martha Chapendeka as a councillor in Neno North.[3] She beat Patrick Kankwatira and Ismael Pius and they both made an appeal to the Malawi Electoral Commission claiming irregularities but the case was dismissed.[citation needed]
In the 2025 elections in Malawi, the number of women in parliament increased from 40 to 48, but in an enlarged parliament. She was elected to be the new chair of the Malawi Parliamentary Women's Caucus in the November. She will serve for two years.[4] The number of women MPs had increased, but the percentage remained at about 20%.[5]
