Matthew Cahill, a structured finance and capital markets partner at Sidley Austin in London, has resigned from the firm after being accused of tax fraud in a film investment scheme.

The charges against Cahill, first noted Friday by U.K. legal publication The Lawyer, stem from allegations made in January against 10 individuals, including a former head of investment advisory at global accounting giant KPMG in London, over their role in a $190 million investment scheme in 2008 reportedly uncovered by British tax authorities after a three-year investigation.
