Speaking in Beijing ahead of the closing ceremony of the Paralympic Games, Mr Johnson pledged to make London’s Games the most accessible ever.
He said he would work with 2012 organisers and authorities across London to ensure the capital was doing everything possible to maximise not only access to the Games but access to the city’s hotels, restaurants, nightspots and other leisure venues.
The Mayor said: “The fantastic achievements of our Paralympic team at the Beijing Games have surpassed the country’s wildest expectations, adding to the pride we all felt watching Team GB reel in their haul of medals last month.
"They have delivered for us - now we must deliver for them, and for all disabled Londoners and visitors. I want everyone who comes London to enjoy every aspect of their stay, including Paralympians, disabled spectators, and anyone who may have difficulty moving around the capital."
Mr Johnson said that meant ensuring a wide choice of accommodation and places to visit during the summer of 2012.
“I urge all London businesses, including shops, restaurants and hotels to start thinking now about they can make their goods and services as accessible as possible in time for and to reap the benefits of the 2012 Games.
"It’s not just about wide doors and ramps in premises - there are a whole range of measures that can be adopted to help people with different disabilities and organisations like the LDA and Visit London are ready and waiting to offer their advice."
