The record, which was released last Friday, has already sold just over 65,000 copies in three days, according to data from the Official Charts Company.

This makes her all-but-certain to secure her third chart-topping album when the final rankings are announced on Friday; having previously hit the summit with 2012’s Red and 2014’s 1989.

Reputation’s sales are reportedly double that of its nearest competition - Sam Smith’s The Thrill of It All - at the halfway stage, and it could well top 100,000 by the end of the week.

Smith is the defending chart-topper, having sold 97,328 in combined physical, download and streaming-equivalent units last week.

If Reputation does top the 100,000 tally by Friday, it will become only the fourth album of 2017 to do so in a seven-day window.

Liam Gallagher’s As You Were bowed to 102,660 last month, Rag’n’Bone Man arrived to 117,101 with Human in February, and Ed Sheeran’s Divide sold an astronomical 671,542 in its first week back in March.

In fact, Sheeran’s opus sold upwards of 100,000 per week for its first five weeks on sale.

Elsewhere, Swift is also selling by the bucketload internationally - and will top 1,000,000 in the USA by the end of the week.

In fact, Headline Planet reports that Reputation sold 717,000 on its first day alone.

It is currently forecast to hit around 1.37 million for the entire week, topping the 1.29 million 1989 achieved in its first week three years ago.

Although this is lower than the rumoured 2,000,000 projection last week, it’s still an absolutely extraordinary number for an album to sell in one single week.

For comparison, the current No1 - again from Sam Smith - posted 237,000, which is itself also a very impressive figure.

Kendrick Lamar’s DAMN. currently holds the one-week record for 2017 in the US, having shifted 603,000 in its first seven days.
