But all eyes were on Labour leader Jeremy Corbyn who wore a poppy and laid a wreath at the Cenotaph in Whitehall – and participated in the singing of the national anthem.

Corbyn had previously attracted wide criticism for not singing the anthem at the Battle of Britain 75th anniversary commemorations, so no one can quite believe he actually sang God Save The Queen.

Some were disappointed with the turn of events and felt sorry for Corbyn.

Others believed it was a great move and thought the Labour leader had done the right thing.

But it wasn’t just the national anthem Twitter was debating about.

It seems a lot of people felt Corbyn hadn’t given enough of a bow when he laid a wreath to honour Britain’s war heroes.

Some thought he hadn’t bowed at all, sparking outrage.

And there were others who felt his bow was only a half-hearted attempt.

Here’s Corbyn’s blink-and-you’ll-miss bow.

It’s subtle, but definitely there.

And here’s a close-up of his signed message on the poppy wreath that said: “In memory of the fallen in all wars. Let us resolve to create a world of peace.”
