It is believed that existing contractual agreements governing the use of the London Stadium grant precedence to a limited number of global sporting events. This clause would allow the World Athletics Championships to take priority over football matches during the designated period.
A spokesperson for the London Stadium acknowledged the potential of the bid and said: "We are delighted that London Stadium is seen as a potential venue for the World Athletics Championships in 2029, one of the biggest events on the world sporting calendar. The 2017 Championships we hosted to sold-out crowds were a huge success, bringing investment and more than £100million in economic benefits to London.
"It is early days in the process for 2029 and full details of any bid are to be developed, including potential dates for the event. During this process we will work closely with all our stakeholders, including West Ham, to make sure any benefits to the venue, city and country are considered fully alongside all other requirements."
