Exhibit 99.1

Leslie Goodman
Chairman

I have pleasure in enclosing our 2006 financial statements.

The encouraging signs seen in 2005 were sustained into 2006 with year-on-year revenue showing a 63% increase. This growth continues to be fuelled by the performance of our UK retail business. It is now our challenge and aim to continue to grow our existing retail business, while also creating value through a successful re-launch of the company’s wholesale business and focussing on potential market opportunities such as for co-location and hosting.

UK Retail

Strong retail sales continued in 2006, with a 64% increase in retail revenue growth by comparison to 2005. In order to support and facilitate this, additional resources were allocated in 2006 to improve the company’s service delivery and fault management capabilities; this has helped us to ensure that our customer churn levels remain below what we consider to be the industry average.

The development of our indirect channel to market continues, with the channel now accounting for approximately one-half of our average monthly sales.

Wholesale

Last year I reported on the efforts we were undertaking to maximise value from our network assets — and on how these had led to the sale of certain of those assets to the Global Voice group, a sale which concluded in June 2006.

As well as providing an immediate cash injection of €18.5m (approximately US$23.7m) and a commitment from Global Voice to share in certain of our ongoing network costs, the transaction also opened up to us market opportunities through our acquisition from Global Voice of metropolitan network assets. Following the transaction, a new wholesale business strategy was developed, designed in particular to maximise these market opportunities and to offer new products at competitive market pricing — our ability to offer such products and pricing being dependent, in large part, on an upgrade of our network infrastructure through investment in new backbone DWDM optical electronics.

The business strategy was approved by the Board in December 2006 and the related investment and upgrade of the network completed in April of this year. The new electronics, installed on the sections of the network connecting London/Paris/Frankfurt/Amsterdam, have enabled us to sell, at market competitive pricing, the 2.5Gbit/s and 10Gbit/s wavelength services increasingly sought by customers.

We began marketing of the new wholesale product portfolio in March under our new VTLWavenet brand name, with additional sales staff being recruited in the UK, France, The Netherlands and Germany.

Financial position

In the fiscal year ended 31 December 2006, our revenues grew to $33.5 million (2004 – $20.6 million) resulting in a lower operating loss of $36.3 million (2004 – $54.9 million) and a lower net loss of $49.5 million (2004 – $63.5 million).

The growth in revenue derived primarily from organic growth in our UK sales but also, in part, to the recognition of annual income arising from the Global Voice transaction. The ongoing losses reflect, in large part, our continuing investment in the retail business, building increased market share and the strength of the Viatel brand, as well as the substantial continuing costs of maintaining and operating the network.

In view of our losses the Company remains reliant upon the continued support of our principal investors to fund its operations. In 2006 and to date in 2007, the investors provided an additional aggregate US$47.8 million by way of debt financing through the purchase of further Increasing Rate Senior Secured Promissory Notes due July 2008.

On the basis of current cash flow expectations, we will require further financing in order to fund our future operations. We anticipate discussing these requirements with our investors before the end of the year with a view to agreeing a refinancing of the existing debt facilities.
