Chief executive Blane Dodds gave an update on the £15m plan at Thursday's annual general meeting in Stirling.

Building work at Greenock's Rankin Park is expected to begin later this year while four other proposals are at the technical design and planning permission stage.

It is hoped two facilities per year can be established between 2020 and 2025.

Tennis Scotland recorded income of £1.97m for 2018, up £110,000 on the previous year.

"Overall it was a very strong 2018 and we have carried that positive momentum into this year, which is already showing a significantly improved financial performance to reinvest in tennis across Scotland," said Dodds.
