Full article copied below. As you can see the distinction between the Wikimedia Foundation and Wikimedia UK is explained further down:

Organisation responsible for Wikipedia already turned down by HM  
Revenue & Customs

Wikimedia UK is to have its application for charitable status  
reconsidered by the Charity Commission after its initial application  
to HM Revenue & Customs was turned down.

Wikimedia UK is part of a global family of national associations that  
coordinate contributors to the Wikipedia website, based in the US,  
and seek permission for other information, such as national archives,  
to be posted.

It applied for charitable status, under the heading of promoting  
education, to HMRC because its annual income is currently below the  
£5,000 threshold for registration with the commission. incompatible

But HMRC turned down the application on the grounds that the mere  
increase of knowledge without teaching or education is not  
charitable. Andrew Turvey, secretary of Wikimedia UK, said: "Museums  
and art galleries are recognised as charities; our argument is that  
what we are doing is analogous to that."

He said HMRC had agreed to pass on Wikimedia's letter of appeal to  
the Charity Commission for adjudication, even though the organisation  
does not expect to have an income of £5,000 for another 18 months.  
Turney (sic) said he hoped for a response within a few months.
