LONDON (MarketWatch) -- The FTSE 100 rose for the first time in three days on Tuesday, as investors waited for U.K. manufacturing data and a speech by Bank of England Governor Mark Carney.

The London benchmark added 0.1% to 6,842.57, after two straight days in the red.

Data: At 9:30 a.m., both manufacturing and industrial production for July come out and will provide some clues as to how the U.K. economy kicked off the third quarter. Economists expect both readings to have climbed 0.3% on the month.

Mark Carney speech: Investors were also eagerly awaiting Carney's speech in Liverpool, scheduled for 11:45 a.m. London time, or 6:45 a.m. Eastern time.

"Traders often use these public appearances to scrutinize his words to potentially gain further clarity and clues on the monetary policies and any changes in the future," said Sam Fox, financial sales trader, in a note.

Movers: Wm Morrison Supermarkets PLC climbed 2.5% after Citigroup upgraded the supermarkets chain to buy, according to Dow Jones Newswires.

Whitbread PLC put on 1.1% after the hotel and restaurant group posted a 12.8% rise in total sales during the second quarter.
