Two of London’s public pension funds are at opposite ends of the league tables for 2015, with strong returns from Kensington and Chelsea's fund contrasting sharply with low single-digit gains for City Hall's fund, until recently chaired by financier Edmund Truell.

Kensington and Chelsea's £826 million pension fund was the top performer out of 101 council schemes for the 12 months ended March 31, 2015. The fund returned 19.1% on its investments, according to its latest accounts, thanks to strong outperformance by global equities manager Longview Partners.
