Britain will not be sending ground troops in to help in the battle against the so-called Islamic State militant group in Syria, Defence Secretary Michael Fallon told ITV News at Ten.
After David Cameron revealed he would "make the case" for the UK to join coalition forces carrying out airstrikes over the country, Mr Fallon said Western troops would "categorically" not be sent in.
Speaking to News at Ten presenter Tom Bradby, he insisted that such a move would be more likely to help radicalise civilians and end up helping IS.
David Cameron has revealed he will "make the case" for Britain to join its allies in tackling Islamic State in Syria, instead of just Iraq.
The Chancellor has said the government will only call a vote on UK military action in Syria when it is "confident that we are going to win".
Labour's shadow chancellor has said the notion of any UK intervention in the Syria conflict has to be looked at in a "very considered way".
