LONDON (Reuters) - Luxury goods group Burberry (BRBY.L) will replace Thomson Reuters (TRIL.L) in the FTSE 100 index .FTSE after the news and financial data company group delists from London, the index compiler said on Monday 7 September.

This change will become effective on September 10.

Burberry was determined as the replacement for Thomson Reuters as the company on the reserve list with the highest market capitalisation.

Thomson Reuters is delisting from the FTSE 100 as it said it wanted to simplify its capital structure and eliminate the persistent discount at which the London shares have traded to North American shares.

The change is separate from the quarterly review of the FTSE 100 which will be announced on Wednesday 9 September after the market closes.

Gem Diamonds (GEMD.L), meanwhile, will be promoted to the mid-cap FTSE 250 .FTMC index, filling Burberry's spot.
