A mother and son admitted arranging a string of “sham” marriages.

Patricia Williams, 60, and her son, Jason Williams, 38, of St John’s Road, Dudley, pleaded guilty to breaching immigration laws when they appeared before Birmingham Crown Court.

The pair were bailed to be sentenced on September 4. They have been prosecuted for arranging bogus weddings to nationals from Africa and Jamaica before.

Last month, eight other people, seven of whom were related to the defendants, were sentenced.

The criminal mastermind behind the scam was Vendrick Clarke, 51. He was sentenced in August last year to nine years in prison for conspiracy to defraud the Home Office, conspiracy to facilitate a breach of immigration laws and one count of supplying Class A drugs.

Jason Williams married Camille Davis, a Jamaican national, in Birmingham in July, 2004.

His mother was said to have attended and supported a number of marriages she knew to be shams.

Other members of the Williams family were sentenced on similar charges last month.

Brett, 31, Daniel, 28, David, 32, Natalie, 26, and Luke, 24, all from Dudley, all received between 12 and 24 months’ jail.

Amanda Williams, 35, from Rowley Regis, West Midlands, received a 12-month suspended sentence and 100 hours’ unpaid work, while Donna Williams, a 37-year-old Jamaican national from Handsworth, Birmingham, who married David, was jailed for 15 months.

Dawn Whitehouse, 33, from Dudley, was given a 12-month suspended sentence and a two-year supervision order for possession of a false driving licence.
