Thomas Cook Group is likely to drop out of the FTSE 100 later this week.
The new list of companies will be published on Wednesday and reports over the weekend suggest Europe’s second-largest tour operator will be demoted to the FTSE 250.
The largest, Tui Travel, is expected to remain in the FTSE 100.
Thomas Cook’s shares dropped to below the £2 mark this morning, which is close to its lowest price in the last year.
The London Stock Exchange is also expected to drop out of the top 100, while Indian power, oil and gas group Essar is expected to enter the elite group, along with gold producer African Barrick Gold.
