Tsipras arrived back in Athens to confront lawmakers from hisSyriza-led bloc who rebelled this weekend when he sought theirendorsement for spending cuts, pensions savings, and tax increases.He met with his closest aides to chart the path ahead, as the Greekparliament faced a Wednesday deadline to pass into law key creditordemands including a value-added tax overhaul, broadening the taxbase to increase revenue and curbing pension costs.
