Pakistan's home series against India have been downgraded to two-Test affairs. Although two Tests are a minimum requirement for a bilateral series to take place, marquee series usually see a minimum of three Tests or more. India and England will be playing five Tests in the series that got underway in Nottingham on Wednesday.
According to the ICC's Future Tours Programme draft, Pakistan will play three two-Test series while hosting India between December 2015 and November 2022. Although any series between India and Pakistan are subject to the political climate, it is unlikely that India will travel to Pakistan to play. In recent years, UAE has been Pakistan's 'home' ground.
Interestingly, when Pakistan tour India - they are scheduled to do so twice between November 2017 and November 2021 - the series will get upgraded to a minimum of three Tests. What's common in all series - there are six series in all - are five one-dayers. In July 2020, Pakistan will host a stand-alone five ODI series. All other series have at least two T20 internationals. India will host an extra T20 international when Pakistan tour in November 2021.
