Deutsche Bank and UBS emerged as two of the largest shareholders in the London Stock Exchange today, having been stakebuilding over the past month. The disclosure comes as the New York Stock Exchange signalled it is prepared to enter the battle for the UK securities market.

UBS, the second largest shareholder in the LSE, raised its holding from 5.9% to 6.1%. Some of the shares were purchased at between 1176p and 1207p.
