A novice MP discovered new technology and ancient tradition do not mix as she landed herself in hot water for taking a photograph inside the House of Lords.
Labour's Liz Kendall whipped out her mobile phone to snap the pomp and ceremony of the Queen's Speech - posting the somewhat blurred result on microblogging site Twitter.
"Haven't quite managed to capture sheer number of diamonds & tiaras," she told followers but soon found the quality of the picture was the least of her worries.
Alerted to the breach of regulations prohibiting photography in the chamber, authorities in the Upper House informed the Serjeant at Arms - who oversees parliamentary security.
A spokesman said the matter was "being dealt with appropriately" but could give no immediate details of what punishment was likely to be handed down to the Leicester West MP.
A somewhat surprised Ms Kendall said she had no idea there was a ban on taking photographs, especially as the event was televised and she had seen an official photographer.
"I certainly did not set out to do anything improper. I just thought I've never ever seen anything quite like this in my life - so much fur and diamonds and tiaras.
"I felt like I was in such a different world I would take a snap," she explained, adding that she had promised to keep her constituency team updated about life at Westminster.
No one had yet contacted her about the incident from the Serjeant's office, she added.
