Oct 9 (Reuters) - Twitter Inc is planning company-wide layoffs next week, technology news website Re/code reported on Friday, citing sources.

The news comes after Jack Dorsey was appointed permanent chief executive on Monday.

It is unclear how many of Twitter's staff will be laid off, but it is likely it will affect most departments, Re/code said, citing company insiders.

The company employs about 4,100 people in more than 35 offices around the world, according to its website.

Twitter's layoffs come at the same time as it restructures its engineering organization to make it more efficient, Re/code reported.

It is likely that many of the people impacted by the layoffs will be engineers, the report said.

"We're not commenting on rumor and speculation," Twitter spokeswoman Natalie Miyake told Reuters.
