Defence Minister and Army reservist colonel Mark Lancaster has visited Kosovo and Serbia for the first time since he served there as part of the British Army.
This is the first visit to Serbia by a British defence minister in more than 10 years.
The trip was an opportunity for the minister to discuss future defence cooperation with Serbia. Mr Lancaster said:
"The Western Balkans is a key region for the stability and security of Europe, and the UK continues to play a leading role in supporting the Kosovo Security Force and the Serbian Armed Forces.
"It is 100 years since we fought side-by-side with Serbia during the First World War, and we will continue to build on our rich history with both countries in the years to come."
The UK has recently boosted its presence in Kosovo, having recently deployed 30 troops to NATO's force there.
The troops are working alongside their allies in the nation in a bid to provide security and stability to the region.
The minister also visited Belgrade, marking the 100th anniversary since British and Commonwealth troops successfully fought alongside Serbian counterparts to secure the Salonika Front during the First World War.
Whilst in Serbia he met defence minister Aleksandar Vulin and laid a wreath at the Belgrade War Cemetery to commemorate Serbian troops killed in combat.
