Er mwyn rhoi cymaint o amser ag sy’n bosibl i awdurdodau lleol baratoi ar gyfer etholiadau 2022, byddaf yn cyhoeddi’r penderfyniadau cyn gynted ag y cânt eu gwneud. Mae hyn yn golygu, o'r wythnos sy'n dechrau ar 21 Mehefin, y byddaf yn cyhoeddi'r set gyntaf o benderfyniadau ar yr adolygiadau. Bydd y Prif Weinidog yn gwneud y penderfyniad am adolygiad Abertawe.
To give local authorities as much time to prepare for the 2022 elections, I will make the decisions public as they are made. This means that, from the week beginning 21June, I will announce the first set of decisions on the reviews. The First Minister will make the decision about the Swansea review because of my constituency responsibilities in my MS role.
