According to The Telegraph:
The Queen has for the first time chosen to use a lift to get to the House of Lords for the State Opening of Parliament, in one of the most public concessions to her age to date.
A spokesman said: “It is a modest adjustment made for the Queen’s comfort.”

It is her 63rd State Opening, and comes less than a month after the monarch celebrated her 90th birthday.
