Luxembourg Finance Minister Pierre Gramegna tells Bloomberg's Caroline Hyde on Brexit that “The most important thing is that we have the U.K. inside the EU." Speaking at the OECD Forum in Paris, Gramegna added that “it’s already been obvious that some decisions on investment have been postponed. So it’s good that the referendum will happen in a couple of weeks to take out this uncertainty.” On Greece, he said “there should be no talk any more about Grexit because it doesn’t make sense anymore.”
