LONDON (Reuters) – Barclays (LON:) has fired the beginning gun on a 1 billion pound share buy-back programme geared toward lowering its share capital after refiling accounts with U.S. authorities on Monday.

The British lender was compelled to resubmit its 20-F accounts after it found in March it had bought greater than $15 billion of complicated securities than it had permission to promote.

The buy-back, which was placed on maintain pending the brand new submission, will begin on Tuesday and finish no later than September 30.

Barclays has instructed JP Morgan Securities to conduct the buy-back.
