A spokesperson for Credit Suisse Group AG said the Swiss lender's official position is not to advise its clients to move their assets out of the U.K. ahead of Brexit, Reuters reported, following a Financial Times report that said the bank's London wealth managers had instructed top customers to do so.

The lender does not hold a "house view" that customers should move assets out of Britain due to Brexit, the spokesperson told the news agency.

The lender's wealth managers in London had contacted customers to advise them to expedite moving assets offshore after U.K. Prime Minister Theresa May in the week of Dec. 10 delayed a vote on her deal to leave the EU, the Financial Times reported.
