The funeral service for the late Queen Elizabeth II is being held today in the United Kingdom.

The landmark event at the Westminster Abbey in London has seen numerous leaders from around the world arrive at the invitation of King Charles III.

In an interesting turn, however, all heads of state and royals were billed to appear at the Westminster Abbey via a bus with the exception of the US president, Joe Biden who was driven in his official vehicle, 'The Beast'.

Though this move raised some eyebrows, it was followed through.

These leaders are there to commiserate with the British people and pay their last respects to the former head of the Commonwealth.

The queen died on Thursday, September 8 at age 96.
