Mehmet proceeds to make things infinitely worse for himself soon after, when he stakes his house and business on a bet, loses and swiftly disappears leaving his wife, Guizin Osman (Ishia Bennison), to face up to the consequences. A then homeless Guzin arrives at Ali and his wife Sue's (Sandy Ratcliff) doorstep with the news that Mehmet had beaten her, and she isn't ever returning to him. Ali and Sue are forced to take Guizin and her three children, Murat, Rayif and Emine (Pelin Ahmet) into their one bedroom apartment. Mehmet returns to Walford in May 1987 and he manages to persuade his long suffering wife to give their marriage another chance. However, his promises to Guizin prove to be hollow as soon after he decides that the barmaid Donna Ludlow (Matilda Ziegler) is to be the next sexual conquest. Donna refuses his advances, but can't resist informing Guizin about his offer and Guizin and Donna nearly fight on New Year's Eve that year. Guizin and Mehmet's marriage is highly turbulent and they are always involved in intense arguments, mainly concerning money and gambling. In 1988 Mehmet and Guzin become partners in Ali's café after Sue gives up working to look after her baby. Mehmet often clashes with his wife about the amount of time he takes off to gamble and the way the café is run. Later in the year Mehmet and Ali run up huge gambling debts to Joanne Francis (Pamela Salem), manageress of Strokes wine bar, and who is also a member of the criminal underworld known as The Firm. Desperate for money the two turn to their café employee, Ian Beale (Adam Woodyatt), for a loan. He agrees, but charges his employers 10 percent interest and later, when they cannot meet the repayments, he demands a stake in the café. The brothers refuse, but the debt eventually leads to Ali losing the café to Ian the following year.
