Chief Adviser Prof. Muhammad Yunus has stated that the interim government hired lawyers to attempt to recover any allegedly stolen funds from the UK, and the British government was "extremely supportive" of this effort.
"I have a lot of admiration for the promptness with which they're treating the whole subject," Prof Yunus told the BBC in an interview during his recent visit to the United Kingdom.
The BBC report says it understands the International Anti-Corruption Coordination Centre (IACCC) is exploring opportunities to assist Bangladesh's interim government and its law enforcement agencies in their efforts to investigate allegations of corruption under Hasina's rule.
Bangladesh authorities estimate that about $234bn (£174bn) was siphoned off from Bangladesh through corrupt means when Hasina was in power.
The Bangladeshi authorities allege that much of this money has been stashed or spent in the UK, reports BBC.
The IACCC is hosted by the National Crime Agency in London. "The NCA does not routinely comment on the nature of international assistance, nor confirm or deny if the Agency has opened an investigation or is supporting a partner's investigation,” BBC quoted an NCA spokesperson as saying.
Prof Yunus did have an audience with King Charles at Buckingham Palace and met Business Secretary Jonathan Reynolds in Parliament.
In a post on X, Reynolds said they discussed "our shared ambitions for economic growth, job creation and prosperity".
Prof Yunus said he had not been able to arrange a meeting with Prime Minister Sir Keir Starmer, a close friend and constituency neighbour of Tulip Siddiq.
"I don't know whether I should be disappointed or he should be disappointed. It's a missed opportunity,” he told BBC.
"That's why I'm saying coming to Bangladesh would be a good opportunity to relax and see and feel the moment."
When asked if Downing Street had given a reason for not scheduling a meeting with Starmer, he said: "I don't think we have received an explanation from that kind of thing. Probably he is busy with other important things."
Prof Yunus arrived in Dhaka on Saturday morning, wrapping up his four-day visit that witnessed a series of meetings highlighting broader and deeper Dhaka-London relations.
