Royal & Sun Alliance (R&SA) is poised to return to the ranks of the blue chips next month, following a sharp rebound in its share price.
According to reports, R&SA is on course to replace services firm Hays in the FTSE 100 index at the next quarterly reshuffle on 11 June.
Index compiler FTSE changes the FTSE 100's membership list four times a year to ensure it represents Britain's biggest publicly-listed companies.
At present, a company's value needs to rise to £1.8bn to join the FTSE. According to Reuters, R&SA is now valued at around £1.95bn following the flotation of its Australian unit, Promina.
