The Treasury Select Committee will take evidence from the deputy governor of the Bank of England (BoE) Paul Tucker and Barclays' chairman Marcus Agius next week.
Both will be questioned on issues relating to the penalties levied against Barclays by authorities in the UK and the US following an investigation into the submission of various interbank offered rates.
Tucker will attend the committee on Monday 9 July at 16.30 BST while Agius will appear at 10.00 BST on Tuesday 10 July.
Tucker was named in a memo from former Barclays chief executive Bob Diamond which suggested that the BoE may have called for it to lower its Libor rate submissions.
As part of a submission prior to his appearance at the Treasury Select Committee, an email from Diamond explained that Tucker had been asked by "senior" Whitehall officials as to why Barclays' rates appeared higher than other banks in 2008. Diamond said that after explaining why, Tucker suggested that did not always have to be the case.
Both sessions will be held in the Wilson Room, Portcullis House.
Further evidence sessions, which have not yet been confirmed, will be announced in due course.
