The top rated Telegraph comment is :
Mr President you are welcome and we look forward to your visit.
Sadly we have amongst us a number of poorly behaved ,
ill mannered and poorly educated people who will be rude to you, your Country,
your people and your family. I think you know this already. Don't give them the
pleasure of acknowledging them.
But on behalf of the insufferable we the decent British people of all ages and
backgrounds apologise if you are offended by anything particularly emanating
from the Speaker of the House of Commons or Mayor of London
(not the Lord Mayor of the City of London who knows how to behave)
We hope you have a great visit and enjoy your time here.
