By George Georgiopoulos and Kylie MacLellan ATHENS/LONDON (Reuters) - Greece cannot make debt repayments to the International Monetary Fund (IMF) next month unless it achieves a deal with creditors, its interior minister said on Sunday, the most explicit remarks yet from Athens about the likelihood of default if talks fail.
