Oliver returned to Parkside Community Primary School in Borehamwood to meet the school council and speak to staff, led by Headteacher Mr Soyka.
Oliver spoke to the school council about his role as an MP and took questions from students on a range of subjects.
Oliver said: 'I hugely enjoyed paying another visit to Parkside Community School and speaking to the members of their school council.
It was impressive to see how engaged these students are, with questions ranging from support for refugees to littering in Borehamwood.
It is always a pleasure to see how hard Mr Soyka and his staff work on behalf of their students.'
