LONDON, Feb 28 (Reuters) - Ocado Group, the British online supermarket and technology group, reported a worse-than-expected full-year loss, partly reflecting profits being wiped out at its retail joint venture with Marks & Spencer .
The group said on Tuesday it made a loss before tax of 501 million pounds ($604 million) over the year to Nov. 27 2022. That compared to analysts' average forecast of a loss of 399 million pounds and a loss of 176.9 million pounds in the previous year.
