asked Her Majesty's Government:Whether, in view of the growing traffic chaos, and the danger of pollution to the Palace of Westminster, they will now consider making this area a "no-go" area to heavy vehicles and coaches.

No. Traffic regulation in London is the responsibility of the Greater London Council. Heavy lorries not requiring access are already banned from the central area of London, which includes Parliament Square. The exclusion of coaches from this area, which includes places of the greatest historical interest, would be hard to justify.
