ATHENS (Reuters) - A referendum on bailout terms that has morphed into a plebiscite on Greece's future in Europe has created the first real splits in Prime Minister Alexis Tsipras' ruling coalition.

Four members of the right-wing Independent Greeks, uneasy bedfellows whose 13 votes Tsipras' left-wing Syriza party needs for a majority, defied him in the space of 24 hours by urging Greeks to accept more austerity in return for cash.
