The letter from LS185 states demonstrators will be dispersed by the protest organisers at 2 pm and the barriers will be dismantled by LS185 contractors.
In advice to security stewards the stadium letter says banners may be used by protesters but must not be offensive and chants cannot be offensive either adding that no protest banners will be allowed into the London Stadium after the static protest has finished.
The letter warns that if protest banners do appear within the stadium they will be immediately removed by security and the owner subjected to potential ejection under ground regulations.
