Greek MPs are debating tough economic measures they must approve by the end of the day in order for an €86bn eurozone bailout deal to go ahead.The new legislation includes tax rises and an increase in the retirement age.PM Alexis Tsipras has said he does not believe in the deal, but has urged MPs to agree to the measures. The vote is expected to pass with opposition help, despite a revolt from some hardliners in the ruling left-wing Syriza party.Pro-European opposition parties have pledged to vote for the measures. Hardliners in the ruling left-wing Syriza party are likely to vote against, and the junior coalition party has offered only limited support. “If I don’t have your support it will be hard for me to remain as prime minister,” Mr Tsipras has told his MPs, as government estimates suggest between 30 and 40 will oppose the measures.Opponents of the deal took to the streets of Athens ahead of the vote, and unions and trade associations representing civil servants, municipal workers and pharmacy owners held strike action.More than half of the members of Syriza’s central committee have signed a statement condemning the bailout agreement, describing it as a coup against their nation by European leaders, according to a news agency.
