Britain's FTSE 100 slipped on Tuesday, as a slump in Rolls Royce shares weighed on the aerospace and defence sector, although miner Glencore limited the losses in the benchmark index following a majority stake deal for Teck Resources.

The blue-chip FTSE 100 was down 0.2% at 0818 GMT, while the mid-cap index dropped 0.1%.

Top decliner aerospace and defence sector fell 0.7%, with a 1.8% slide in Rolls Royce shares after the Emirates President Tim Clark challenged the engine maker to improve durability and lower maintenance costs.

Glencore rose 3.4% after the miner agreed to buy a 77% stake in Canadian miner Teck Resources' steelmaking coal business for $6.93 billion in cash.

The industrial metal mining sector climbed nearly 2% on the news, leading sectoral gains.

The media sector gained 0.5%, with a nearly 5% rise in Informa shares after the events organiser increased its full-year revenue and profit expectations.

Data showed British wages grew slightly less fast in the third quarter, but remained close to their record pace, doing little to ease the Bank of England's concerns about inflation pressures.
