* FTSE 100 up 0.2%, FTSE 250 adds 0.4%
Sept 15 (Reuters) - London's FTSE 100 climbed on Tuesday as
upbeat industrial output data from China powered shares of
trade-exposed miners, while online supermarket Ocado surged on
reporting a jump in quarterly retail sales.
The blue-chip FTSE 100 was up 0.2% with Rio Tinto
, BHP Group and Glencore providing the
Ocado Group rose 6.2% to the top of the FTSE 100
after saying its retail joint venture with Marks & Spencer
posted a 52% jump in revenue in the 13 weeks to Aug. 30.
The mid-cap FTSE 250 rose 0.4%.
The index, considered a barometer of Brexit sentiment, has
underperformed the FTSE 100 this month following Prime Minister
Boris Johnson's plan to breach the Brexit treaty with the
European Union. The proposal won initial approval in the UK
parliament on Monday.
