The Footsie is expected to open around 24 points lower this morning, tracking falls overnight by US and Asian markets following some disappointing corporate earnings, with tech giants Apple weak following numbers released after-hours. The FTSE 100 index closed 19.62 points lower yesterday at 6,769.07, with European markets nervous ahead of a key vote today in the Greek parliament on a second package of reforms required to secure a crucial third bailout deal from the European Union.
