Input: Mr. Khosrowshahi  visited London as the company  he  was chosen to lead just weeks ago continued to grapple with a new set of issues. Uberâs board is considering proposals to limit the power of its co-founder and former chief executive  Travis Kalanick  as it courts a major new investment.
While  Mr. Khosrowshahi  is on  his  diplomacy mission  Uberâs board is scheduled to discuss proposals that would limit Mr. Kalanickâs power. That meeting will include two new directors named by Mr. Kalanick late last week  a surprise move that escalated tensions with other board members.
It is a sign of the importance of the London ban that  even with Uberâs board meeting set to take place   Mr. Khosrowshahi  flew here to meet with the authorities. With 40 000 drivers and 3.5 million customers  the city is Uberâs biggest market in Europe  and one of its largest in the world.
The effort on Tuesday is meant to show that Uber is adopting a more conciliatory approach to working with cities. Such a change in attitude is important as Uber continues to expand globally and justify its sky-high $68.5 billion valuation ahead of an initial public offering that  Mr. Khosrowshahi  has said could come in 2019.
