Sir Elton John performed for an audience which included both the King and the Prime Minister at a major investment summit in London.

The music legend and former Watford FC chairman was the musical guest of honour at an exclusive reception at St Paul's Cathedral yesterday.

Sir Elton recently reflected on his own mortality, with the 77-year-old admitting "I don't know how much time I have left".

The lifelong Hornets fan makes the revelation in Elton John: Never Too Late, an upcoming Disney + documentary which premiered last week.

As well as a performance from Sir Elton, guests at the summit were provided with food from Michelin-starred chef Clare Smyth.

The event was compered by Bridgerton star Adjoa Andoh.

After the summit, Sir Elton sat down with Prime Minister Keir Starmer and took to Instagram, posting: "An important night at the International Investment Summit in London and an honour to perform at St. Paul's Cathedral to global leaders, including  the Prime Minister."

Starmer hosted the summit as part of a bid to woo investors and set out of his vision for growth after a tricky few weeks for his government.

In his speech, the PM announced deals which he claims will create around 38,000 jobs.
