Massive cheer for Venezuela, who are having a proper party as they dance along the side of the track.

In comes Ukraine, bedecked in yellow and blue - and flower crowns! Loving that. They've even colour co-ordinated the flowers with the outfits, which is a level of detail that I appreciate.

We're almost at the end of the parade as Turkey make their way in. Ten of their 14 Paralympic medals came in 2012 - this time around, they have 106 athletes looking to better that record.

Russia have been banned from the Paralympics but they've made an appearance after a member of the Belarus team waved a Russian flag.

The flag was on display for a quarter of the circuit before being confiscated.

The IPC said they were working to identify the offender before deciding on any action.

So while the athletes enter and the jigsaw in the centre builds, these guys are standing patiently with the flags. They get bonus points for all swaying in perfect synchronisation.

In come Syria, led by Mohamad Mohamad. His legs were amputated at the age of 10 after he stepped on a landmine.

Here comes Sierra Leone, led by George Wyndham. Wyndham contracted polio as a child, leaving him in a wheelchair and he has lived in the national stadium as he struggles to support himself.

Prince Harry has played a part in these Paralympics after making a donation to the #FillTheSeats initiative.

The campaign aims to help Brazilian children watch the Rio Paralympics.

As it stands, ticket sales have risen to 1.5 million from a total of 2.5m.

The Maracana is now a mixed shade of red and green and still the athletes are coming. We'll finally get to see what that jigsaw looks like, too...

P brings us Poland, and their flagbearer is Rafal Wilk. Cyclist Wilk used to be a speedway rider but after an accident he competes as a handcyclist. He's also had a film made about him.

In comes the Netherlands. They're led by 'Blade Babe' Marlou Van Rhijn, who is  a world record holder over the T44 100m and 200m sprints.

Norway might win the award for the best outfits. Superbly co-ordinated suits decorated with their national flag.

The jigsaw is still going strong: one side has an image of the athletes from each country, the other with the country's name. We're up to N now with Namibia, with their nine athletes led by Johanna Benson, who won gold in the T37 at London.

Sir Philip Craven, the president of the International Paralympics Committee, admitted that Rio has given him some sleepless nights.

"These are the people's Games and we're going to have a fabulous time here," he said.

"I think the organising committee in Rio were in a state of stress.

"I averaged three hours sleep in 21 days. On the last day, on 22 August, before I left for a break back in Britain, I didn't eat for 19 hours and that caused me to pass out on the plane for 15 minutes before it took off.

"I woke up and thought 'what's the bother about, I feel fine now'. But it was a really stressful time."

Halfway through the alphabet now with Madagascar. Just the four athletes but they have great straw hats with their country's name emblazoned on the front. They're followed by Malaysia, in bright orange suits.

There's plenty of ParalympicsGB talent out in Rio, and David Weir is one of the most well-known faces.

He went from being a 'skinny kid' (Baroness Tanni Grey-Thompson's words, not mine!) to a four-time gold medallist at London 2012.

The wheelchair racer will be in action from Sunday 11 September, competing in the first of his five events.

And now enter Japan. It's their turn next in 2020. Will they see a rise in talent when it's their time in Tokyo in four years? They'll be very proud hosts.
