Reynolds says UK is committed to 2.5% of GDP defence spending targetpublished at 09:37 Greenwich Mean Time 16 February
Asked if the UK has troop numbers to support Ukraine if it comes to a peace-keeping mission with boots on the ground, Reynolds admits it would be a massive ask.
He says "we shouldn't downplay" the abilities of the armed forces but says there's a lot more to do.
Reynolds also insists the UK is committed to increased defence spending and meeting the 2.5% of GDP target.
Pressed on the "roadmap" planned for defence spending, Reynolds says a spending review is underway, and that there had been a substantial increase in the last budget.
He adds it's not unreasonable for the US to expect Europe to increase defence spending.
