The organisers of the London 2012 Olympics have won a legal battle over the land for the proposed Olympics site.
They are now allowed to buy that land, and force some businesses currently occupying the area to vacate their premises.
Compulsory Purchase Orders (CPOs) were confirmed by Industry Secretary Alistair Darling.
Manny Lewis, Chief Executive of the London Development Agency (LDA), said:
"Whilst we have been granted the CPO powers, we will continue to negotiate with landowners in an effort to reach agreements.
We have already managed to secure 93% of the land through negotiation and the LDA is on course to deliver an incredibly complex project on time."
The LDA claim that around 70 businesses may have trouble moving and some jobs may be lost, but the Olympics would lead to an extra 11,000 jobs in the area.
