Every 'foreign' Scotland star in Six Nations squad's eligibility explained including key star van der Merwe

Scotland will hope to return to winning ways when they head to Twickenham to take on England in their latest Six Nations clash this weekend.

Gregor Townsend’s men claimed a home win against Italy on the opening weekend of this year’s tournament before falling to a defeat against reigning champions Ireland earlier this month.

With all eyes now focused on Saturday’s meeting with their oldest rivals, Scotland will be hoping to claim the Calcutta Cup for a fifth consecutive year - and the form of Duhan van der Merwe is sure to be essential after the South African-born wing star produced several impressive displays against England in recent years.

Much like the Edinburgh wing, there are a number of other players that qualify for Scotland via their parents that have featured in both Six Nations fixtures - and here is how they are eligible to take their place in Townsend’s squad.
