The leaders at this year's G7 summit look weaker than ever

• The G7 summit is exposing a crisis of Western authority, experts say.
• Far-right parties are gaining ground in several countries, and leadership appears to be weakened. 
• Many leaders at the G7 summit face uncertain political futures.

The G7 summit has long been a showcase of global leadership and power.

The world's seven largest "advanced" economies — the US, Canada, France, Germany, Italy, Japan, and the UK — gather each year to discuss issues such as the economy, security, and trade.

But 2024's group of leaders appears to be one of the weakest that has attended the summit for some time.
