Yes, it probably is, especially as it's expecting the pro-Heathrow George Osborne to make the announcement. The article did include this however.
Justine Greening, the Tory MP for Putney and International Development Secretary, has promised to continue fighting against expansion at Heathrow.
She has told her constituents that she has been assured by Patrick McLoughlin, the Transport Secretary, that there will be a new public consultation on plans before a final decision is taken.
The high costs of expanding Heathrow and the impact on the environment, including noise and air pollution, remain the subjects of considerable argument.
Not sure what McLoughlin's alleged assurance refers to or 'final decision' means. There is an impression perhaps from this and previous comments he remains to be convinced.
Sounds like it might be approved in principle subject to various qualifications that will drag the thing out.
