Now heading the BNP from exile, Tarique is convicted of money laundering and corruption in two separate cases.
He is also being tried in many other cases, including one on charges of attempted assassination of Hasina.
“The UK is a free country, anybody can take shelter, refuge…that’s true. The crime that the person committed… and already he is convicted,” Hasina said.
“And I don’t understand how UK enjoys keeping a convicted person,” she had remarked.
Hasia also said her government was “eager” to take Tarique back.
BNP Senior Vice-Chairman Tarique, in London for a decade, is standing in for his mother Khaleda Zia who was jailed for five years for corruption on Feb 8.
He has also been sentenced to 10 years in prison in the same case. He had earlier got a prison term of seven years for laundering money.
