Bad taste to some, being honest to others.No reason why she shouldn't - and then keep her motivations to herself ! Just stupid for an MP who swears an allegiance to the crown to then make happy public statements whilst the queen's consort is being buried. It is just in extraordinary bad taste and a poor use of the public platform she enjoys as an MP, which is why it shows a complete lack of talent and whit.
And as for swearing an allegiance to Brenda, that is unfortunately a prerequisite of being able to sit in the HoP. Another anachronism that should be ditched as I suspect many Labour, SNP and other MPs simply do not agree with or believe the words that they are required to say.
