Boris Johnson was wearing a specific lapel pin during Prime Minister's Questions today (Wednesday, Thursday 26), which most other MPs were also wearing.

This caused some individuals on social media to ask what the lapel pin signified.

The small purple pin was being worn by the Prime Minister and others ahead ofย Holocaust Memorial Day on Thursday, January 27.

On the Holocaust Memorial Day website, it says: "Holocaust Memorial Day is the day for everyone to remember the millions of people murdered in the Holocaust, under Nazi Persecution, and in the genocides which followed in Cambodia, Rwanda, Bosnia, and Darfur."

It aims to give voices to people who have survived various genocides and to educate people on the terror and suffering that the genocides caused.

The badges are available to buy on the Holocaust Memorial Day Trust website, although it will be a bit late to order some in time for the day this year.

Boris Johnson had been under pressure again in PMQs to resign amid a scandal of another party that had taken place on the Prime Minister's birthday.

What was the initial reaction to the lapel badge?

One user on Twitter was initially confused by the badges saying: "Does anyone know what the lapel pin, being worn by MP's at #PMQs today, represents?"

Another user was happy to reply informing them that it was for Holocaust Memorial Day.
