Mounting guard honour barcelona discloses reason refusal

I think there may be a bit of a misunderstanding here!

Mounting the Guard of Honour is a ceremonial tradition where a military unit presents arms to a dignitary or a head of state. It's a symbol of respect and honor.

Barcelona is a city in Spain, and I'm not aware of any specific instance where the Guard of Honour was refused in Barcelona. Could you please provide more context or clarify what you're referring to?

If you meant to ask about a specific event or incident where the Guard of Honour was refused in Barcelona, I'd be happy to help you find more information.
