It appears to be poacher turned gamekeeper season among the capital’s chief executives.

First there is Mark Davies, who has gone full circle after being confirmed as interim chief executive at Imperial College Healthcare Trust. He was there at the west London giant’s inception, then head of provider development at NHS London – helping trusts like Imperial reach foundation status – and he is now back on the other side of the table at Imperial.

Then there is the new head of provider development at NHS London. John Goulston, who as former chief executive of problem trust Barking, Havering and Redbridge University Hospitals, used to sit opposite Mr Davies at FT status chivvying meetings.

Their positions round that table will now be reversed.

The chief executive shuffle moving clockwise round London has seen a potentially confusing bunch of leadership changes.

It has put NHS Harrow and Brent boss Mark Easton in Barnet and Chase Farm; former Barnet and Chase Farm boss Averil Dongworth at Barking, Havering and Redbridge; and Mr Goulston, the aforementioned Barking, Havering and Redbridge chief executive, at London HQ in Victoria Street.

Departing Imperial chief Steve Smith rather spoils the whole pattern by going to Singapore.

Mark Easton is not the only former primary care trust boss to have landed in a contentious acute now the cluster dust has almost settled.

Former NHS Newham boss Melanie Walker has gone to Essex’s Princess Alexandra Hospital and NHS Westminster’s

Michael Scott is now interim chief executive at Walsall Hospitals – both trusts with less than entirely certain futures.
