Reporting directly to 3 UK CEO Bob Fuller he will be responsible for assessing the commercial viability of new business opportunities.
"Having worked with Gordon for more than 10 years I am confident he will lead the company successfully into new market segments" said Fuller.

The acquisition makes Go Mobile the industry´s fifth largest independent dealership with 35 stores. The stores will be re-branded as Go Mobile. Go Mobile takes on around 30 staff from A1 Comms.
Go Mobile managing director Iain Humphrey said: "The purchase of A1 Comms makes absolute sense. The footprint works well for us. We will keep growing the chain in a good professional manner. There is good business out there for independent dealers that write the type of business that the networks want with regard for ARPU and tenure."
A1 Comms managing director Paul Sisson said that only 30 per cent of the company´s revenues came from its retail footprint. The remainder came from corporate and web sales both of which have much lower overheads than retail.
"The bottom line is that running 10 shops on the high street is very difficult" said Sisson. "You are better off having either many more outlets or much fewer. Iain Humphrey is in a much better position to make a success of it because his chain of stores is larger. The sale is in the interests of both me and my staff."
Sisson will continue to run B2B sales under the A1 Comms brand and will spin off the web sales business www.buymobilephones.net as a separate limited company on June 1.
A1 Comms retains its Orange OBS and O2 Advanced dealership status.
"B2B is great because the networks love you because they love B2B customers" he added. "We gets lots of support and that business is going from strength to strength. We sell up to 100 phones a day from the web site. We are keen to concentrate our efforts and grow these businesses."
Nine of the 10 A1 Comms stores are in Derbyshire and one is in Nottinghamshire.

His shock departure follows weeks of high-level departures at the firm and adds fuel to rumours of a management rift in the company.
Despite this being the latest in a lengthening list of departures a Vodafone spokeswoman continued to deny reports of unrest at the company. "I can confirm that Chris Tombs will be leaving the company but it is to take up a new role elsewhere" she said.
Andy Smith CEO of Anglia Telecom and a former colleague of Tombs at Vodafone said: "Chris will be a massive loss to the business. Someone needs to look at why so many people are leaving."
Vodafone regional sales manager Chris Brenchley is also rumoured to have left the company.
Tombs and Brenchley are the latest in a long line of Vodafone figures rumoured to be leaving as the result of management differences with director of enterprise business unit Kyle Whitehill. Recent departures include Chris Huggett and Richard Hurring who both left the company in the past couple of months.
Other high-level departures over the past year include marketing manager Peter Bamford finance director Ken Hydon and senior manager for business partnerships Jason Rigby.
Next month Sir Julian Horn-Smith and Lord MacLaurin will also retire from the board. Their departure will mark the last of Sir Christopher Gents so-called "Newbury boys". Gent who oversaw the firms rapid expansion in the 1980s also symbolically severed ties with Vodafone in March by stepping down as president for life after he reportedly disagreed with CEO Arun Sarins management policy.
"Vodafone UK has lost a huge amount of talent over the past three years people who had the vision and passion to put Vodafone where it is today" said Smith.
Sarin now faces a battle to regain control as Vodafone announced record losses over £15 billion last week. This follows a rocky few months for the company that included the sale of Vodafone Japan in March.

"What´s great about ticketrush is that our customers get tickets to these gigs before anyone else so they don´t miss out."
