Lord Patten is free to become the new chairman of the BBC Trust, after rumours of an attempt by the Conservative right to stop the move were put to rest.
Right-wing Conservative backbenchers were alleged to have been opposed to Lord Patten's appointment due to his pro-Europe stance.
However, the party's Eurosceptic lobby has dismissed the rumours of a challenge to the appointment as an attempt to increase speculation that Lord Patten was not a certainty for the position.
David Cameron is expected to announce Lord Patten as the trust's new chairman within days, following a recommendation by culture secretary Jeremy Hunt.
Lord Patten will then go before the House of Commons culture, media and sport select committee on 10 March for a "pre-appointment hearing," where he is expected to be approved for the position.
