Question to the HM Treasury:

To ask Her Majesty’s Government which will be the lead regulator responsible after the acquisition of the London Stock Exchange by Deutsche Börse.

As announced by the companies in February 2016, the existing regulatory framework of all regulated entities within the combined group would remain unchanged. This is subject to the regulatory review which will take place once the regulators are notified by the companies.

European Regulation No 648/2012 (EMIR) requires coordination amongst regulators for supervisory and authorisation matters with regards to CCPs.
