To his congregation, he was an inspirational Christian pastor who had dedicated his life to raising money for the poor, homeless and sick.
Isaac William, 61, his wife Venus, 54, and their three daughters appeared to be the very model of Christian charity, funding housing, hospitals and education in Pakistan.
But in reality, the preacher at St Nicholas Church in Tooting, South London was swindling taxpayers out of £2.6million in a tax fraud to pay for a million-pound property empire in Britain and abroad.
The ‘crooked’ businessman who ran a security guard company, made profits of over £6million exploiting illegal immigrants who were forced to work around the clock on a pittance and live in cramped caravans and huts sleeping on the floor.
To avoid paying VAT, income tax and national insurance, William hid the profits into a number of bank accounts including his charity account named ‘The Great Commission Evangelical Fellowship’.
But the money was then withdrawn in cash and laundered by his wife and daughters, Sylvia, 34, who worked for Lloyds Bank, Maria Gunasekara, 33, a business manager for Barclays and their younger sister Sophie, 26, a law graduate.
