Quotation mark usage in the sentence given

A leading article in Britain's Independent newspaper has the following (my emphasis):

It is also evident, albeit in a different form, in the Global Investment Summit that opened on Thursday with a rousing speech from the Prime Minister full of assurances about "getting behind" British business.

I have some confusion in understanding this statement. Are the words which are enclosed in quotation marks showing irony? Or is it just that the quoted words (by the source) are being quoted again by the author? Or is it that the author doesn't have the same opinion as did the source had in the meaning of the words? Also please provide me with some important points in understanding quotation marks and their uses as I am a non-native learner.

Solution 1:

There are two factors governing the use of quotation marks here.

First, as Rory Alsop confirmed, this is a direct quotation of Cameron. Probably from this speech:

There’s another way we are getting behind business — by sorting out the banks. Taxpayers bailed you out. Now it’s time for you to repay the favour and start lending to Britain’s small businesses. (Source)

Second, getting behind is somewhat colloquial — more colloquial, at any rate, than is typical for The Independent. So, even if it weren’t a quote, they might well put scare quotes around it, to signal that they are aware that it is out of register.

Solution 2:

I think in this case the quotes indicate that 'getting behind' were the actual words used by the Prime Minister.
