'Curry Queen' Held For Smuggling Illegal Immigrants   One of Britain's richest business-women of Pakistani origin has been arrested for allegedly smuggling illegal immigrants into the country to work for her chain of restaurants. Fifty-two-year-old, Nighat Awan, was held "on suspicion of conspiracy to facilitate illegal immigration", the national press reported recently. A government race adviser, closely linked to former Prime Minister Tony Blair's wife Cherie, Awan, owns the Shere Khan chain of restaurants in Britain and has been dubbed the 'Queen of Curry'. In February, her husband, Rafique Awan, was arrested in the same probe. He was interrogated after the police searched the couple's four-million-pound 'White House-style' mansion in Hale Barns, Cheshire. As part of the police operation targetting organised immigration crime, 70 suspected illegal immigrants were also arrested in February during raids on a number of Indian restaurants, several in the Shere Khan chain. Last year, Awan was appointed as head of a Department of Trade and Industry-backed group to support black and ethnic minority businesses. She is also a close ally of Jack Straw, the Justice Secretary, and was awarded an Order of the British Empire (OBE) three years ago. Three years ago, Cherie Blair was guest of honour at a garden party held by the Awans. The entrepreneur and her family have also toured Downing Street on a number of occasions during the former PM's regime.
