I think you are right to point out that couples like these face riducule and discrimination.
That cannot possibly be justified .
I am 5ft 6ins and my OH 6ft so we have never encountered that type of discrimination but we do have friends whose height difference is the other way round.
He is a very strong character, as is she and I think that may also apply to Mr and Mrs Bercow.
I don't condone bullying and I think that if John Bercow was found guilty of bullying staff he should have been punished accordingly and treated the same way as Pritti Patel, also proven guilty of bullying.
Having said all that I must say I thought Bercow was an excellent Speaker, safeguarding Parliament at a time when it was under attack by the forces of Brexit, backed by Mr Vladimir Putin.
Sadly his protection of the rights of MPs was not enough to protect our democracy from the malign influence of Russia and we were taken out of the EU, de-stabilising the West in accordance with the wishes of the Kremlin
