PwC's new outpost is in such close proximity to E&Y's HQ, the Big Four leader is said to have installed window blinds which close automatically for presentations

PwC's new offices near More London are so close to Big Four rivals E&Y that the incoming tenant is taking steps to preserve its trade secrets.

In 2007, PwC decided to build an office, which at its closest point is approximately 10m away from Ernst & Young's HQ.

To ensure highly confidential information is kept within company walls, PwC has installed blinds which automatically close when audio visual presentations are taking place, according to the Daily Telegraph.

E&Y is also "evaluating a number of options," according to the paper.
