LONDON, July 16 (Reuters) - Ocado, the British online supermarket and technology group, on Tuesday reported a lower first half loss and raised its financial guidance for the full year.

The group said it now expected its key technology solutions division to achieve a "mid-teens" EBITDA margin in the full 2023-24 year, versus previous guidance of over 10%. It also forecast underlying cash flow would improve by 150 million pounds ($194 million), ahead of a previous expectation of 100 million pounds.
