Shares in BSkyB rose on the possibility New Corp could be forced to sell its 39 per cent stake in BSkyB.
The share price increase came as Ofcom said that it has the power to remove BSkyB's broadcasting licence, saying that it would take into account the MP report on the £12bn pay-to-view company.
Shares rose prior to BSkyB's operating profit for the nine months to the end of March, which was valued at £939m, up 25 per cent from the same period last year.
BSkyB said: "The impact of this year's price freeze [was] more than offset by our success in selling our home communications products to new and existing customers."
"The decision to focus our marketing on home communications has paid off with our fastest quarter of growth since launch and confirmation that Sky is now Britain's favourite triple play provider," said chief executive Jeremy Darroch.
