London 2012: GB women's second Cardiff football game

After Friday night's spectacular opening ceremony in London, Olympics sport will return to Cardiff's Millennium Stadium later on Saturday.

The Welsh capital will host Great Britain women's football team for a second time when they play Cameroon.

Fans are warned to arrive early after problems with bag searches and ticketing on the first two days.

Elsewhere, Wrexham-born rower Chris Bartley is the first Welsh competitor in Olympic action for GB on Saturday.

He is part of the lightweight coxless men's four who enter London 2012 as a real medal hope, with GB rowing off against the Czech Republic, Australia and Germany.

Team GB kicked off events in Cardiff on Wednesday when they beat New Zealand.

Roads around the Millennium Stadium will be closed between 12:00 and 20:00 BST and Arriva Trains Wales said Cardiff city centre stations would operate differently when games were being played.

Two games will be played on Saturday at the stadium: New Zealand v Brazil at 14:30 BST, followed by GB v Cameroon at 17:15 BST.

A crowd comparable to the first two days of action is expected for the double-header with just over 30,000 attending on Wednesday and almost 27,000 on Thursday.

Six further football matches will take place at the stadium over the course of the Games including Great Britain men's and the men's bronze medal final.

Cardiff hosted the first event of the entire Olympics on Wednesday and there was a carnival atmosphere with street entertainment in the city centre ahead of the match.

The launch of the Games was hailed as "fantastic", and London 2012 chairman Seb Coe said Cardiff felt like "an Olympic city".

Traders say they believe the Olympic football has given businesses in Cardiff city centre a boost at a difficult time of year.

Fans praised the city and the stadium but some pointed to teething problems as long queues formed where security teams were searching people's bags.

On Thursday, there were no problems with bag searches but large queues formed at ticket booths a couple of hours before kick off.

Many fans were unhappy having to wait an hour to pick up tickets they had already ordered and paid for online.

The Olympic Games are now in full swing after Friday's opening ceremony.

More than 50 schoolchildren from Wales formed part of the guard of honour as the athletes arrived into the Olympic Stadium.

The voices of children from Wales as part of Only Kids Aloud were played at the stadium singing Cwm Rhondda.

The ceremony was watched at outdoor big screens, including in front of 15,000 people in Colwyn Bay.

The Access All Eirias show featured live music from the likes of Only Kids Aloud, Sophie Evans and Mike Peters, in between the screening of major moments from the opening ceremony live from London.

While the opening ceremony took place at Stratford, rock band the Stereophonics represented Wales at a celebration concert in Hyde Park.

Earlier on Friday, the Red Arrows aerobatics display team flew over Wales, starting from RAF Valley on Anglesey at 15:58 BST and arriving in Cardiff 23 minutes later.
