Deutsche Bank has disclosed a stake of at least 7% in Merlin Entertainments after underwriting a £660 million block trade for the UK owner of the London Eye and Legoland, in what was a tense week for auctioned block trades in Europe.

The German bank disclosed the holding to the London Stock Exchange on Friday. Earlier in the week the bank had agreed to underwrite the sale of shares in Merlin Entertainments on behalf of private equity firms CVC Capital Partners and Blackstone Group. It is not clear how much of the holding is linked to that deal.
