A Midland MP tipped to become the country's first Asian Prime Minister accepted nearly £12,000 from a failing nursing home on behalf of his constituency office.
Critics have called on Culture Secretary Sajid Javid to give back the money and questioned his judgement in accepting the donation from the Moundsley Hall Care Home in Birmingham.
Mr Javid, Tory MP for Bromsgrove, registered that he had received the £10,975 in donations to his local constituency party from the home on 29 May last year.
The Care Quality Commission (CQC) report, which found that the care home was failing, was released on 3 May 2013.
A subsequent inspection in August 2013 found these problems had not been remedied and Moundsley Hall was issued with a compliance notice demanding improvements.
Four months later Mr Javid's local constituency office, which pays for its candidate's electioneering, received another £675 from Moundsley Hall.
Labour MP for Warley John Spellar said: "I am shocked that Sajid Javid has taken donations from a care firm failing its patients.
"He now needs to rapidly answer how much he knew about this when he received the money and to seriously consider whether he should give it back.
"His constituents in Bromsgrove and the public in the wider West Midlands will demand a swift answer."
Jessica Hosmer-Wright, Parliamentary Assistant to Mr Javid said: "This donation was made by a local business to Bromsgrove Conservative Association, and not to Sajid.
"Nevertheless, Sajid believes that it's good practice for MPs to be open and transparent about political donations, even when they are made to their local association."
A spokesman for the CQC said: "A final warning notice to implement our recommendations was issued to Moundsley Hall care home in March 2014.
"Since then our inspectors made a discreet visit to the home and are in the process of compiling a report on their findings which will outline whether or not the owners have complied.
"That report is subject to any legal challenges and then will be published on our website in due course."
Moundsley Hall was not available for comment.
The CQC report from May 2013 said the home had failed to meet four of its nine quality criteria including failure in providing adequate care, staffing and management.
The publicly available report said it took until 12pm each day to get people washed and dressed and that "the registered provider did not have appropriate systems in place to ensure that staff received professional development to ensure people's safety".
It added: "People did not experience care, treatment and support that met their needs and protected their rights" and "there were not enough qualified, skilled and experienced staff to meet people's needs".
An unannounced CQC inspection in January this year discovered its recommendations had not been fully implemented.
The assessment concluded: "The registered provider had not taken appropriate steps to protect the people against the risk of care or treatment that was inappropriate or unsafe.
"The provider had not taken reasonable steps to ensure the safety and welfare of people that lived there. The individual needs of people that lived there had not always been met.
"The provider did not always carry out assessments of people's needs when their needs had changed."
Moundsley Care Home, owned by Moundsley Healthcare which made the donations to the Bromsgrove Conservative Association, including a £5,000 payment in 2006, is a private nursing home providing accommodation and care for the elderly who may have physical or mental health related illnesses.
