Sanford “Sandy” Weill, the former head of Citigroup Inc., has stepped down as chairman of Hamilton Insurance Group, the Bermuda-based company backed by quantitative hedge fund firm Two Sigma Investments.

Weill, 82, is retiring effective immediately, and will be replaced as chairman by Chief Executive Officer Brian Duperreault, the insurer said Wednesday in a statement. Weill will still advise the company as a consultant on growth initiatives, Hamilton said.
