Japanese telecoms firm Softbank, is reportedly interested in investing a billion dollar stake in Uber, just a day after investing $2bn in rival Grab.

According to The Wall Street Journal, the Japanese technology company has approached Uber about taking a stake in the ride-hailing firm, with sources cited by the publication saying that the offer could cause confusion between global competitors following its investment in multiple similar companies.

According to reports, the talks between Softbank and Uber are in the early stages and is expected to be ‘weeks away.’ No deal would be agreed until Uber has appointed a new chief exec, according to the Wall Street Journal report.

Uber has faced a series of knockbacks this year, following the resignation of CEO Travis Kalanick after investors requested new management share. Additional changes to the company include Uber board member Arianna Huffington emerging as the public face of the company.
