Inmarsat, the UK-listed satellite communications company, enjoyed its biggest rise in three months after International Airlines Group (IAG) announced plans to install high-speed internet on its narrow-body, short-haul aircraft.
The in-flight broadband service, provided by Inmarsat, will be available to passengers on 341 jets across all of IAG’s carriers. The first plane to be fitted will be a British Airways A321 next summer. The news sent shares in Inmarsat flying 2pc higher, although they ended the day up 0.9pc at 730p.
Elsewhere in the mid-cap index, security firm G4S shot up 10pc to 242p after it reported high third quarter sales growth, driven by good trading in the US. Drugmaker Indivior, which was spun out of Reckitt Benckiser and is headquartered in the United States, topped the index, ralling nearly 11pc after raising full-year sales forecasts for its opiod addiction treatment, Suboxone.
