"I am simply overwhelmed...no actor has ever been given this privilege...I am blessed," the 71-year-old actor wrote on his Twitter page.

Bachchan was also invited to take a tour around the Houses of Parliament.

"Speakers House over 1000 years old, unimaginable structure and interiors ... what an honour, a most rare opportunity to be there," he wrote, adding, "And a rare visit to the Monarch's bedroom ! Where the to-be- Coronated King or Queen spends the night before the crown is put on."
