London, March 30 : British Home Secretary Jacqui Smith has been fighting to salvage her credibility and future political career following the humiliating admission that she claimed taxpayer-funded allowances for the cost of two porn films her husband enjoyed at her family home, while she was away in London.

According to reports, the episode has threatened to further undermine Gordon Brown's Government, which has been blighted by a series of expenses controversies in recent weeks.

Not only Jacqui's political position is under scrutiny after this event, but her marriage is also said to be in jeopardy as a result of the row.

Her public humiliation comes at a time when she is already under investigation by the Parliamentary watchdog for claiming the share in the house she rents from her sister as her "main residence".

Meanwhile, the Sunday Express says that a leaked copy of Jackie's Additional Costs Allowance (ACA) shows that the couple were also reimbursed for two other films, and items totalling thousands of pounds like televisions, washing machines, a kitchen sink and even an 88p plug.

Under the rules, the Home Secretary has to confirm that all expenses refer to costs accrued in the course of her work as an MP.

Jackie has apologised for the claims and vowed to repay the amount.

Her husband Richard Timney also regretted about the embarrassment he had caused to his wife.

"I am really sorry for any embarrassment I have caused Jacqui. I can fully understand why people might be angry and offended by this," the Telegraph quoted him as saying.

"Quite obviously a claim should never have been made for these films, and as you know that money is being paid back," he added.

The adult films were viewed at 11.18pm on April 1 and 11.19pm on April 6, while Jackie was staying in London. (ANI)
