"The LSE suspended the admission of the GDRs to trading on 3 March 2022 and the Company has received no indication since that trading may be recommenced," TCS said in a statement on Tuesday.

"Accordingly, the Company hereby requests to proceed with the Delisting in order to avoid the ongoing commitment of time and resources necessary to maintain the LSE listing. The Company intends to terminate its Rule 144A GDR program promptly following the Delisting."
