Great Britain made a winning start to their Fed Cup campaign with victory over Portugal in Tallinn, Estonia.
Wins for Heather Watson and Johanna Konta gave Britain an unassailable 2-0 lead in the first Group C match.
They go on to face Latvia on Thursday and Turkey on Friday, with the group winners earning a play-off against the Group B winners on Saturday.
The winners of that tie will progress to a World Group II promotion play-off in April.
Britain are seeded third among the 14 nations in Tallinn and first in their group, and Portugal were unable to overcome the gap in rankings.
