The FT called on me for a comment this afternoon, following the news that David Cumming has quit Standard Life Investments.

Cumming is head of equities at Standard Life Investments and his departure comes only days after the announcement that Standard Life is to merge with Aberdeen Asset Management.

Whenever big companies merge, some turbulence is inevitable.

We don't know the reasons why Cumming has chosen to leave Standard Life Investments now - Standard Life declined to comment on the reason for his departure. - but his resignation is certainly a blow to the group and bad timing so close to the merger announcement.

His track record as a fund manager in the UK equities space is enviable; second best over the past five years in the UK All Companies sector.

It will be interesting to see over the coming weeks and months whether this is an isolated resignation or the start of a larger number of departures from Standard Life and Aberdeen.
