It seems very likely BG shareholders will follow suit on 28 January and if so the deal is expected to complete 15 February.
Shares in Shell are down 0.4% at £14.15 but off session lows of £13.80 ahead of the meeting in the Hague. BG is up 1.1% to £10.06.
Turnout at the vote was 61.24% with 83.08% voting in favour of the combination and 16.92% voting against.
Commenting on the shareholder vote, Ben van Beurden, CEO of Shell, says: 'I am delighted with the positive shareholder vote and the confidence that shareholders have shown in the strategic logic of the combination of Shell and BG.
'Our immediate focus is on the successful completion of the transaction and we now await the results of tomorrow’s BG shareholder vote.'
