TUI TRAVEL has rejoined the FTSE 100 stock index after more than a year as a mid-cap firm, while newly-floated Direct Line clinched a FTSE 250 ranking.

FTSE Group said in its quarterly reshuffle that water company Pennon, which has lost around 15 per cent of its market value in the period, will be demoted to the FTSE 250 when the new rankings take effect on 24 December.

At the bottom end of the corporate league table, Ruspetro, Talvivaara and Shanks Group have all sunk below the market capitalisation required to remain in the FTSE 250 and will be relegated to the small-caps.
