Protests are expected this afternoon in south Wales ahead of a Nato summit later this week.
The Stop the War Coalition's 'No to Nato' demonstration is set to go on until the end of the summit, which runs over September 4th and 5th.
The Stop the War website says the 60 leaders, including President Obama, are meeting to "plan their war on the world".
It is expected that the crisis in Ukraine and how to respond to alleged Russian aggression in the region will be high on the agenda at the summit.
Were the Russians -as Barack Obama claims - weighed down by sanctions, or where the Ukrainians looking to cut their losses?
The new president of the European Council could be "very important" for David Cameron.
