Uber: co-founder Travis Kalanick to resign from board of directors

• Former CEO to step down by end of year, effectively severing ties
• Kalanick had been subject of shareholder revolt after setbacks

Uber's former CEO Travis Kalanick will resign from the board of directors of the US ride-share giant by the end of the year, the company said on Tuesday, effectively severing ties with the outfit he co-founded a decade ago.

Kalanick, who helped found Uber in 2009, stepped down from the company's helm in June 2017 under pressure from investors, after a string of setbacks.
