Prince Charles is inviting an A-list of Indian billionaires for a series of working lunches and formal dinners in London in a bid to enlist their support for some of his favourite charitable causes.

Charles has invited Mukesh and Anil Ambani, Ratan Tata and K.P. Singh and others for meetings at Clarence House and Kensington Palace next month, the Sunday Times reported.

The paper quoted unnamed sources close to the Prince as saying that the causes include protecting the environment, preserving historic buildings and supporting the young jobless throughout the Indian subcontinent.

The Prince's British Asian Trust is to stage concerts, sporting events and fashion shows and invest in local charities and communities to 'help them to help themselves', the paper said.
