[10] Lewell-Buck joined the All-Party Parliamentary Group on Hunger and Food Poverty chaired by Frank Field and the Bishop of Truro.

After the report Lewell-Buck said in Parliament "Food poverty is a clear consequence of the Government's ideological assault on the social safety net and the people who rely on it.

[18] In October 2016, she was re-appointed to Jeremy Corbyn's front bench team as Shadow Education Minister responsible for children and families' policy.

[25] Due to the calling of the 2019 general election, the reselection process could not be completed in time and she was re-selected without a local party vote taking place.
