FRANKFURT, March 24 (Reuters) - Aspex, a top Delivery

Hero shareholder, on Tuesday urged the online takeaway

food group's supervisory board to oust the CEO and his top

management team in an escalation of the investor's campaign for

a change in strategic direction.

"Wholesale changes in the management team will be required

to address issues faced by the company," Aspex Management said

in a letter addressed to Delivery Hero Chair Kristin Skogen Lund

and other members of the non-executive supervisory board, which

was seen by Reuters.

"Fellow shareholders share our view that (CEO) Niklas Oestberg's

strategy is flawed, and that Delivery Hero's operational

underperformance against peers is accelerating," the letter

said, adding that the company was to be heavily burdened by

compliance and control failure.

Delivery Hero said it acknowledges the latest letter from

Aspex.

"We are progressing with the strategic review and it remains

an ongoing core focus of both the Management and Supervisory

Board," the company said in a statement in response to the

letter.
