Sir the same partnership question which I posted in it was mentioned that In January 20X8 Sam received £10,000 from the partnership’s bank drawn on its overdraft facility. He told the bank that the money was to finance a short-term partnership debt but in fact he used the money to pay for a round-the-world cruise.

Sir here Sam has express authority for borrowing money or does he has implied authority for borrowing money?
