LAWYERS for the Catalan Government have said it is essential that a nominee for president must be physically present in the parliamentary chamber for debate and voting.

In an advisory report, the legal experts said regulations prevented a president being sworn in at a distance — via Skype, for instance — as deposed President Carles Puigdemont planned to do from exile in Brussels.

Former vice president and leader of the pro-independence ERC, Oriol Junqueras, is still in a Madrid jail, as is deposed Catalan Home Affairs Minister, Joaquim Forn.

All were re-elected as MPs in the December 21 election called by Spanish Prime Minister Mariano Rajoy, but a judge has denied them permission to be released to vote in today’s opening session of parliament. Six other former cabinet ministers spent a month in jail and were released on bail of up to €100,000 (£88,700).

Puigdemont, who is facing charges of rebellion, sedition and misuse of public funds, would face immediate arrest were he to return from his self-imposed exile in Belgium, which is why his party — Together for Catalonia (JxCat) — wants him installed as president through Skype.

A European Union committee meanwhile, has received more than 40 requests from Catalans to investigate the political situation in Catalonia and the Spanish state police violence surrounding the October 1 independence referendum. The requests have been sent to the Committee on Petitions.
