The Conservative Party said it was reviewing its Facebook ad after being accused of misrepresenting a BBC News story.
The BBC logo was advertised in an advertisement titled "A financial boost of £ 14 billion for schools".
But a BBC article related to advertising said the figure was £ 7.1 billion.
Full Fact, a charity that verifies the facts, said that political parties should not "misrepresent the work of independent journalists in this way."
A Conservative Party spokesman said: "Our intention was not to give a false statement using this title copy with the news link, where the BBC's £ 7 billion figure is clearly displayed but we are looking at the correspondence between the titles of our ads and their links. "
By clicking on the advertisement, readers have discovered the original story of Sean Coughlan, published on the BBC News website, titled "A Financial Boost of Several Billion Pounds for Schools".
The BBC's analysis in the August 30 article questioned the government's assertions regarding its additional funding for schools.
The company's statistics officer, Robert Cuffe, explained here that the government was not calculating the increase in spending in the usual way.
"By describing this as an increase of 14 billion pounds, the government would seem more generous than it really is," he wrote.
The announcement of expenditure has provided £ 2.6bn extra next year, £ 4.8bn the following year and £ 7.1bn in 2022-23.
Together that represents £ 14 billion, but that's not how spending increases are normally calculated, Mr Cuffe said.
Since budgets are normally discussed for each year, he stated that the usual practice is to measure the increase in spending over a year, usually the last one where the increase is greatest.
Mr. Cuffe told the BBC: "Independent experts examine the effect of increased spending on a department's annual budget.
"The addition of these increases over many years exaggerates the generosity of the government.It is an old ploy of political accounting used by many governments."
Full Fact stated that various versions of the ad with the modified title had recorded between 222,000 and 510,000 impressions, although they could include multiple visualizations of the same person.
A spokesman for the BBC said: "We are examining this case".
