The leaders met Charles, the Duke of Rothesay, after the Kirking of the Scottish Parliament in Edinburgh on Wednesday.

Dugdale dared Rennie to ask him what he gave the Monarch as a 90th birthday gift, with the Prince looking taken aback by the question when he was introduced to the Lib Dem leader by outgoing Presiding Officer Tricia Marwick.

The Lib Dems confirmed Rennie's £100 winnings have already been donated to Edinburgh's Gorgie City Farm.

We're still waiting to hear how Prince Charles responded exactly.
