June 3 (Reuters) - JPMorgan Chase ( JPM ) has given

Marianne Lake, widely seen as a potential successor to CEO Jamie

Dimon, the additional responsibility of managing its overseas

consumer banking arm and strategic growth office, according to

an internal memo on Tuesday.

The change comes as incumbent Sanoke Viswanathan resigned as

the CEO of JPMorgan's ( JPM ) international consumer and wealth unit.

Viswanathan will join as the CEO of FactSet from

September, the financial data provider said.

Lake is currently the CEO of JPMorgan's ( JPM ) domestic consumer

and community banking arm, which serves more than 84 million

consumers in the United States.

JPMorgan's ( JPM ) international consumer banking business has

gained over 2.5 million customers in the UK, and is set to

expand across continental Europe and beyond, CEO Jamie Dimon and

President Daniel Pinto said in the memo seen by Reuters.

Viswanathan, 50, spent more than a decade at the Wall Street

giant, and was also a member of JPMorgan's ( JPM ) operating committee.

He also oversaw the bank's international private bank and

workplace solutions businesses within the asset and wealth

management unit.

While leading JPMorgan's ( JPM ) strategy for many years,

Viswanathan oversaw many of the bank's investments and

acquisitions.

Dimon, 69, said on Monday that his retirement was "several

years" away, adding that he might stick around for a couple of

years as chairman or executive chairman.

Bloomberg News reported the development earlier in the day.
