Millions walk in worldwide women's marches

Close to 700 marches have been held around the world, with organisers estimating more than 4.5 million people have taken part.

Thanks to the international dateline, New Zealand was the first to rally, complete with reminders of New Zealand's place in the history of political representation for women.

In London, a crowd filled Trafalgar Square.

All across the United States, women took to the streets

Social media - and streets - struggled to contain the marchers.

But it wasn't just big cities.

Nor good weather.

And, of course, politicians got in on the act.

This is a good question.
