The owner of a fish and chip shop empire who headed the UK end of a human trafficking ring has admitted using his business to smuggle people into the UK.
Balwinder Singh Chatha, 44, of Dorrington, Shrewsbury, will be sentenced at Wolverhampton Crown Court.
He was involved in the trafficking of Sikhs from the Punjab through Paris and into the UK, police said.
His sister-in-law Bakshinder Chatha, 35, and Charan Singh, 48, from Leicester, will also be sentenced.
All three face the court again in mid-December for breaching immigration controls.

His sister-in-law was described as having a "support role" and looked after the immigrants when they arrived in the Shropshire area and did his accounts.
Some of the illegal immigrants were housed above the fish and chip shops and at his home.
Singh was a customer who paid for an immigrant. He was stopped by officers on his way back to Leicester.
All the immigrants who were detained have been dealt with by the Immigration Service.
The operation follows information from another gang who were smuggling people
into the UK for Chatha's gang. They were jailed in May this year for a total of
