Williamson presided over a ticketing operation at the 2012 Olympic and Paralympic Games which sold 99.9 per cent of its available stock online, with key marketing decisions encouraging a full take-up of tickets even for sports not widely popular in the host nation, such as handball, where the entire complement of 250,000 was sold.

He has now been tasked with heading up ticketing for London 2017, scheduled to be held next summer in the Queen Elizabeth Olympic Park, having already played a part in crafting the event’s strategy on that front.

"I am delighted to be part of a great team working hard to deliver the biggest sporting event of 2017," said Williamson, who was also ticketing director for last year’s Rugby World Cup in England.

"I am confident that yet again the British public will be enthused and excited by London 2017 and I am looking forward to filling stadia across both championships to really build on the passion and legacy of 2012."

Another appointment made by London 2017 is that of Lucy Crickmore, who takes up the role of protocol manager.

Crickmore will be focusing on the delivery of all official congresses, meetings and functions, as well as managing the in-stadium VIP and hospitality provision for both championships.

She joins on secondment from UK Sport, where as a consultant for the past eight years she has worked with national governing bodies to manage UK Sport’s investment into and provision of technical support for major events.

As a member of the athletics team during London 2012, Crickmore managed International Federation services.

"I am very excited about joining the London 2017 team as we prepare to host these key championships," she said.

"I witnessed many magical moments in the Olympic Stadium during London 2012 and I look forward to being part of a team that will provide an environment where the world’s best athletes can once again produce those inspirational performances to make the nation proud."

The two latest appointments come on the back of high ranking civil servant Sir Robin Young being named co-chair of the London 2017 Organising Committee last month.

Sir Robin, who headed the Department for Media, Culture and Sport as permanent secretary between 1998 and 2001 and the Department for Trade and Industry from 2001 to 2005, is serving alongside fellow chair Ed Warner.

It came after a raft of recent problems within the Committee with managing director Sally Bolton stepping aside earlier this year along with fellow Board members Heather Hancock and Martin Stewart after allegations of a power battle with UK Athletics chair Warner and chief executive Niels de Vos.

It was thought that conflict of interest claims had arisen with Warner and De Vos also working at UK Athletics, as chairman and chief executive respectively.

Baroness Tanni Grey-Thompson, an 11-time Paralympic gold medallist, resigned from the Board as she felt her role was "tokenistic".

Cherry Alexander has replaced Bolton as managing director, but concerns remain over the lack of sponsors for the Athletics World Championships, due to take place from August 4 to 13.

Speaking about London 2017's latest appointments, Alexander said: "We are putting together a first-class team to deliver these World Championships next year. 

"In the time that Paul and Lucy have already been on the project, they have already brought experience and expertise from delivering at the very highest level at recent major events hosted in the UK.

"It is a real coup to secure their commitment throughout the rest of the delivery of the championships and I am looking forward to working with them over the coming months as we work towards hosting an incredible summer of world class athletics in 2017."

The World ParaAthletics Championships, which are being staged in the same city and the same summer as the World Athletics Championships for the first time ever, are due to take place from July 14 to 23.
