The London Stock Exchange and Deutsche Boerse have issued a joint statement saying Brexit makes their proposed merger “ever more important” and they remain “fully committed” to the deal.
A “referendum committee” has been set up to consider the implications of the UK vote to leave the EU.
Joachim Faber, chairman of the supervisory board of Deutsche Boerse and chairman of the Referendum Committee, said: "The decision of the UK to leave the EU makes it ever more important to maintain and foster ties between the UK and Europe.
“We are convinced that the importance of the proposed combination of Deutsche Börse and LSEG has increased even further for our customers and will provide benefits for them as well as our shareholders and other stakeholders."
Donald Brydon, chairman of the board of the London Stock Exchange and chairman designate of the combined group, said: "I look forward to working with my new colleagues to create an industry-defining combination which will be a leading global market infrastructure business anchored in Europe."
