Egyptian opposition parties have formed a coalition against proposed changes to the constitution that would allow President Abdel Fattah el-Sisi to stay in office beyond the end of his current term in 2022.

Egypt's parliament has given its preliminary approval of the changes after two-thirds of the general committee endorsed the proposed amendments on Tuesday.

The 596-seat assembly, which is packed with Sisi supporters, will take a final vote on February 17, but the amendments would also need to be put to a national referendum.
