Nathan, who has cerebral palsy and uses a wheelchair, wrote to the Prime Minister after watching a disabled girl on the news having to be physically lifted into Number 10 - because there was no wheelchair ramp.
A Downing Street spokesperson confirmed that the portable ramp had been temporarily moved in the news item.
Nathan immediately contacted Mrs Burt, and offered his support for Scope's campaign.
"Nathan is a remarkable boy and he fully deserved to be chosen to co-present the pledges from Scope's national campaign for equality for disabled people.
"The pledges demonstrate public commitment to ending disablism. However, we all realise that there is still a lot of work to be done before disabled people enjoy the same life chances pledged by the Government as non disabled people enjoy without a second thought."
Nathan was accompanied to London for the day by his Mum and Dad, Donna and Andre, and enjoyed a tour of the Palace of Westminster and Tea on the Terrace with Mrs Burt before listening to debate in the House of Commons to round off his big day.
