LONDON, Nov 8 (Reuters) - Britain's top shares fell on Monday as mining and energy stocks tracked lower commodity prices, while financials eased on Basel III and sovereign debt concerns.
Rolls-Royce rose 2.7 percent after the enginemaker announced progress in understanding the cause of the failure of a Trent 900-powered A380 Qantas flight on Nov. 4, adding the incident was specific to that type of engine.
The incident has rattled a global aviation industry recovering from heavy losses during the downturn, and has been damaging for Rolls-Royce, its shares having dropped nearly 10 percent.
The FTSE 100 closed down 25.39 points, or 0.4 percent, at 5,849.96. It hit a 29-month closing high on Friday after investors cheered the U.S. Federal Reserve's commitment on Wednesday to boosting growth.
"Trading has been pretty listless in light volumes, as the market consolidates after the sugar rush of Fed induced volatility of recent days," Jimmy Yates, head of equities at CMC Markets said.

Investors will watch for the the Bank of England quarterly inflation report on Wednesday and Governor Mervyn King's news conference for any indication on the central bank's own quantitive easing programme.
