The Home Office is investigating a claim that immigration officials have granted visas to foreign nationals in exchange for sexual favours. The British tabloid newspaper, The Sun, reported the allegation by a former administration officer at the Lunar House immigration processing centre in Croydon, South London. He also alleged security checks were lax, making it easier for potential terrorists to sneak into the country. A Home Office minister said he was confident staff were professional. "I have every confidence that staff within the Immigration and Nationality Directorate carry out their roles with professionalism and integrity," Tony McNulty said. "There are clearly established systems for staff to raise any concerns that they may have with working practices within their team and to take the issue further if they feel it is necessary." Mr McNulty added that the allegations were "serious" and he would ensure they were investigated fully. Reprinted from bbccaribbean.com
