Unibet have extended their contract as title sponsors of the Unibet Premier League for 2021 ahead of the conclusion of this year's tournament on Thursday.
Unibet have supported the Premier League since 2018, during which time the roadshow event has grown to include a visit to Berlin, a double-header in Rotterdam and featured the innovative Challengers concept.
The 2020 season saw the first six nights played in front of live crowds before the event resumed in August with the remaining ten league nights behind closed doors in Milton Keynes.
This year's champion will be crowned on Thursday night in the Play-Offs in Coventry, with the 2021 season set to commence in Cardiff on Thursday February 4.
"We thank Unibet for their continued support of our widest-reaching tournament," said PDC Chairman Barry Hearn.
"This year has seen the tournament staged under unique circumstances but has been as captivating as any season, which is a tribute to the players involved.
"Whilst this season will end on Thursday with the Play-Offs, we can already look ahead to the 2021 Unibet Premier League with anticipation."
Neil Banbury, Kindred's UK General Manager, said: "We are delighted to extend our partnership with the PDC to sponsor the Unibet Premier League for a fourth consecutive year in 2021.
"Unibet shares the PDC's commitment to innovation and excitement and we look forward to offering darts fans exclusive offers and markets which have made us an industry-leader in sports betting.
"The stage is set for even more thrilling Thursday nights and we're proud to be part of the action."
