CAIRO (Reuters) - To Hisham Genena  the assault appeared well-timed. Egypt’s former anti-graft chief was on his way to appeal against the disqualification of President Abdel Fattah al-Sisi’s strongest potential challenger in an upcoming presidential vote.
 Sisi ’s office referred questions to the electoral commission.
 Sisi  faces a single opponent in the election who has said  he  supports the president.
In a speech announcing  his  candidacy last month   Sisi  said: “I promise you that the next presidential elections will be a model for freedom and transparency  and that there will be an equal opportunity for all candidates.”

Fannie and Freddie buy mortgages and package them into securities with a guarantee against default.
 Fannie and Freddie have a legal right to return bad loans  especially if they later discover fraudulent statements on applications. Any money they recover offsets their losses.
 A bigger headache for lawmakers is figuring out what to do with Fannie and Freddie in the future.
 The Obama administration is working on a plan to restructure the mortgage market and make sure home loans are affordable. Officials don't plan to release details until next year. But Michael Barr  an assistant Treasury secretary  told the panel Wednesday that Fannie and Freddie "will not exist in the same form as they did in the past."
 Republicans have seized on the administration's management of Fannie and Freddie to illustrate Democrats' push for broadening the reach of the federal government. They say loans acquired by Fannie and Freddie since the September 2008 takeover have put taxpayers at risk.
 But Democrats and regulators say the loans acquired by Fannie and Freddie before their takeover represent the overwhelming majority of the companies' losses. New loans acquired since then have been performing well  they note.
 "There is no urgency " to reform the two companies  said Rep. Barney Frank  the committee's chairman. "The pattern of abuse they had engaged in has been changed...Fannie and Freddie are behaving differently and are causing far less problems."

HONG KONG/BEIJING (Reuters) - Chinese e-commerce firm Alibaba Group (BABA.N) has taken control of logistics unit  Cainiao  and pledged to spend 100 billion yuan ($15 billion) over five years to build out a global logistics network  underscoring aggressive expansion plans overseas.
Alibaba will invest 5.3 billion yuan to boost its stake in Cainiao Smart Logistics Network to 51 percent from 47 percent  giving it direct control over the loss-making affiliate  suggesting a rough valuation of  Cainiao  at around $20 billion.
âOur commitment to  Cainiao  and additional investment in logistics demonstrate Alibabaâs commitment to building the most-efficient logistic network in China and around the world â Alibaba CEO Daniel Zhang said in a statement on Tuesday.
 Cainiao  was the focus of an investigation last year by the U.S. Securities and Exchange Commission (SEC) into Alibabaâs accounting practices.
 Alibaba  which will gain an extra seat on Cainiaoâs board giving it four out of a total seven seats   added that more shares were issued in the funding round to other investors.  It  did not give details about the other issuances  which would impact  Cainiaoâs  valuation.
The investment also signals  Alibabaâs  intention to boost control over China âs  domestic warehousing and delivery market  increasingly competitive as firms seek to make use of troves of logistics data about the countryâs Internet-savvy shoppers.
In June major logistics company SF Holding cut ties with  Cainiao  which provides logistics support directly to Alibabaâs top e-commerce platform Taobao . SF Holding claimed Alibaba had requested data unrelated to an existing partnership agreement. Alibaba denied the claims.
A person close to Alibaba  who asked not to be named  said  Cainiao  was not currently considering an IPO.
Alibaba and  Cainiao  declined to comment.
Alibaba co-founded Cainiao in 2013  with partners including department store owner Intime Group  conglomerate Fosun Group and a handful of logistics companies. It oversees roughly 57 million deliveries a day.
