Jeremy Corbyn met with the Prince of Wales on Wednesday for a secretive meeting. However, the circumstances of the meeting have not yet been specified.
The news came hours after Corbyn revealed that he would not be watching the royal wedding live on Saturday.
It is usual for Prince Charles to meet with the leader of the official opposition, with His Royal Highness having three private meetings with Ed Miliband over the span of his leadership. However, it has taken Corbyn nearly three years to meet with the Prince.
The Labour leader, who is a Republican, is due to address his party’s economic conference on Saturday, while Prince Harry and Meghan Markle tie the knot at St George’s Chapel in Windsor.
A senior Labour spokesman was asked if Mr Corbyn would be watching the royal wedding on television.
The spokesman replied: “There’s catch-up, isn’t there?”
The clash between Labours economic conference and the royal wedding means that Corbyn will be unable to watch the wedding live.
However, the spokesman said that Corbyn “wishes them all the best and he is a particular admirer of the work Prince Harry and Prince William have done in relation to mental health issues”.
At Prime Minister’s Questions, Theresa May offered her best wishes to the couple.
She said: “I’m sure the whole House will wish to join me in offering our best wishes to His Royal Highness Prince Harry and Meghan Markle on their wedding this Saturday and the very best for their future lives together.”
Considering Mental Health Awareness Week Mrs May praised Harry’s “tireless work” in raising awareness about the challenges faced by service personnel as they move into civilian life.
Mr Corbyn echoed Mrs May’s praise by sending his wishes to the couple and thanked Harry “for the work he’s done in highlighting the need to challenge the stigma surrounding mental health, and the ability of all of us to talk about mental health to ensure people don’t suffer in silence on their own – particularly young people who are so often grievously affected by this.”
