“Without the reference to a June review  Russia would have been tied to the end of 2018; it wanted instead to have an escape clause ”  Petromatrix strategist Olivier Jakob  said.
“It leaves a question mark about the second half [of 2018] and about the commitment of Russian oil companies  which will be price dependent ”  he  said.
The CEO of Russia’s top private producer Lukoil told Reuters  he  would like to see the price of oil stable at current levels  trading in the $60-65 per barrel range.
The oil market is unlikely to overheat   he  added  thanks to cooperation between OPEC and its allies which would allow them to release new output into the market to rebalance it.

Greg Johnson  one of Anxo's cider-makers   attaches an air of romance to cider.
"There's something special about apples that  like  a husk of corn doesn't have "  Johnson  says.
Wine has long had its connoisseurs. With the rise of the craft beer movement  drinkers have learned to appreciate the nuances of that brewed beverage  too. But cider  in many drinkers' imagination  remains an unrefined  blandly sweet drink  says  Johnson . The reality is far different   he  says.
"There's a whole expansive world  just as expansive as beer  just as expansive as wine. I just keep working to show people that "  Johnson  says.

Premier Silvio Berlusconi is steeped in a new scandal over a dinner he had at the home of a constitutional court judge who will rule on a key decision whether to grant him immunity from prosecution while in office.
 Opposition lawmakers have called for the removal of the judge  Luigi Mazzella  and a colleague who participated in the mid-May dinner  saying there would never be any way to know whether Berlusconi influenced their deliberations on the immunity issue.
 The court began debating the constitutionality of a law last month that grants Berlusconi  the Italian president and two parliament speakers immunity from prosecution. Berlusconi's forces had pushed the legislation through parliament last summer  saying it was necessary for the government to function.
 At the time the bill was passed  Berlusconi was on trial on corruption charges in Milan  fueling criticism that the bill was tailor-made to save him from prosecution. The premier's trial was suspended pending a decision from the constitutional court  which is expected soon.
 Cabinet minister Elio Vito defended the premier  saying Berlusconi hadn't organized any meeting about the legislation but was rather invited to a dinner by a friend well before the court began deliberating the case.
 Berlusconi has long been dogged by conflict of interest allegations as well as corruption charges stemming from his years as a billionaire media mogul. He has either been acquitted -- sometimes thanks to laws passed by his own government -- or seen cases against him expire under the statute of limitations. He has always maintained his innocence  claiming he is the victim of a conspiracy of left-leaning magistrates.
