BT is mulling the launch of a price war with BSkyB by slashing the cost of televised sport in the UK. The telecoms giant is considering undercutting the subscription for Sky's sports channels by £10 a month, according to reports this morning, and will charge £15 a month for Sky Sports 1, compared with the £25.50 that Sky currently charges. Regulator Ofcom is said to meeting this week to discuss the whole issue of Pay-TV. BT and rival Virgin Media hope the regulator endorses its preliminary inquiry findings that Sky should reduce its wholesale prices by up to 30%. A decision is expected from Ofcom in March, though if it goes against BSkyB, it is also certain to appeal, which could delay a decision past the start of the next football season. That would dash BT's hopes to offer Sky's sports channels by the start of the next football season.International Power tops the rises on weekend press reports that French power giant GDF Suez has made a takeover approach to the energy group.The Sunday Times reported that International Power and GDF Suez have been in talks for months, though none of the companies has so far commented on the rumours.
