HMRC have announced:

A Protocol delivering comprehensive exchange of information up to OECD and international tax standards between Switzerland and the UK, which covers UK taxes of all kinds, was signed in London today by The Financial Secretary to the Treasury, the Right Honourable Stephen Timms MP and the Swiss Ambassador to the UK, His Excellency Alexis P Lautenberg.

Useful.

Decades too late of course.

And I remain quite unconvinced that OECD standards are good enough. Only Automatic Information Exchange will provide the smoking gun to eliminate abuse in Switzerland — and we are a long way from it.
