Lamont signed a two-year deal and will join Northampton in the summer from Glasgow.

Lamont, 24, scored for Glasgow against Northampton in the European Cup earlier this year and is a physical, hard-running winger that Saints head coach Budge Pountney is delighted to have on board.

''He has shown us already this year what a raw talent he is in the European Cup when he tore teams apart, including us, with his incisive runs,'' said Pountney.

''He is in the mould of a big, physical winger with pace and a high work-rate but also proves to be very elusive on the rugby pitch. We are very much looking forward to working with him here at the Saints.''

Northampton also completed the signing of Percival from Premiership rivals Worcester. He too will join up at Franklins Gardens during the summer.

Percival played for England Under-21s in last year's Six Nations campaign and the Under-21s World Cup.

I am really pleased to be signing to Northampton. It is a good club and a step up for me, which should enable me to improve my game, he said.
