MPs on the cross-party Treasury Committee will quiz the boss on Tuesday afternoon on the demise of Greensill Capital, which jeopardised 5,000 steelmaking jobs in the UK.
The committee’s inquiry is also investigating how Mr Cameron lobbied Chancellor Rishi Sunak over access to Government-backed coronavirus loans for Greensill.
Ahead of his appearance, the MPs are expected to publish correspondence received from the subjects of the inquiry after they were issued with a series of questions.
A series of investigations is under way into the role the Conservative played in securing Whitehall access for Mr Greensill.
Among the demands, committee chairman Mel Stride requested a full timeline of contacts that Treasury officials and ministers had with Mr Cameron and other Greensill representatives
The senior Tory MP also asked Mr Cameron to share the full texts he sent the Chancellor, which the Treasury has declined to publish.
